Lulu Guinness  teamed with artist Joseph Steele for a painterly pick. The limited-edition clutches  ($465) are available July 11. If you love the splattered style, get yours quick — only 180 (each signed and numbered) were produced.
July 10 brought the first glimpse of the highly anticipated K-Way x Versus collaboration. Among the offerings, a reversible windbreaker  ($495), with two options: a streamlined solid and a bold black and white print.
The K-Way x Versus iPad cover  ($125) would definitely dress up your tablet. Of the collaboration, Donatella Versace  noted, "The jacket and iPad case are an amazing new way to get the Versus Versace look, and to bring attitude and energy to everyday essentials."
We love Vans for being our go-to brand for comfy sneakers, and we love it even more for its supertrendy collaborations (remember when the brand teamed up with Kenzo ?). Now Vans has partnered with Liberty Art Fabrics for a paisley- and floral-inspired collection. Featuring six Liberty fabrics on two Vans styles, these sneakers  ($60) are the best of both worlds.
Karl Lagerfeld will put another notch in his collaborations belt on July 5 when Net-a-Porter  begins selling a capsule collection  he created with Tokidoki . In addition to an adorable doll-size version of the designer and his beloved cat Choupette, the collection also includes t-shirts, jeans, and an iPhone case decorated with a Lagerfeld-inspired cartoon print.
Jane Mayle , the designer whose handbag business shuttered in 2008, is back in action. She has come together with Club Monaco  to create a collection of cool-girl bags . Shop two crossbody options, a colorblock satchel, a clear pouch, and a straw tote that's perfect for summertime fun.
Here's another one we love: this blue-striped Mayle bag  ($495). It's classic with a heritage feel, and it was made for weekend getaways.
What happens when Eddie Borgo designs for Dr. Martens ? You're looking at it! This collaboration is the reason you're witnessing the coolest pair of lace-up boots you've seen in a long time. Fork over $1,450, and they can be yours.
Design guru Jonathan Adler  has joined fashionable forces with TOMS for a sunglasses collection  just in time for Summer. You can choose from three equally cool options, and of course, for each pair purchased, the company will donate another to someone in need.
O'2nd , one of South Korea's most popular brands, has teamed up with Uniqlo  for a capsule collection of Summer-ready dresses that are feminine with a touch of masculinity. One of our favorite pieces is this denim dress featuring a neon belt  ($40). But we also love this perfect striped dress  ($30). Want to see more? Shop the complete collection  now.
Photographer Mario Testino — founder of the MATE Asociación charity — has created a capsule collection exclusively for Net-A-Porter called Mario Testino for MATE . The lineup includes colorful caftans, printed t-shirts, totes, and clutches. The jewelry was designed by Vicki Beamon, and is a direct interpretation of Peruvian craftwork. Worth noting: a percentage of each purchase will be donated to Testino's charity.
The tops and totes feature abstract and enlarged photographic prints from Testino's Alta Moda exhibit, which opened in April in Avenido Pedro de Osma in Lima, Peru. Alta Moda is a series of photographic portraits of Peruvians wearing traditional and festive attire from the mountainous region of Cusco, and to create the exhibit, Testino made several trips to Cusco over a five-year period.
J.Crew  has become quite good at partnering with brands and designers — now formally called "In Good Company" — that fit the retailer's preppy-cool bill. And its latest collaboration with swimwear brand Pret-à-Surf is exactly what we want to be wearing all Summer long. The 11-piece collection includes swimwear, shorts, and rash guards ranging from $150 to $210, and you can snag these pieces now .
Pret-à-Surf for J.Crew hipster in polka dot  ($150)
When two of our favorite labels collide in a high-low mix, it might just look like this: Suno x Uniqlo . The capsule includes  a line of shirts, dresses, skirts, and jeans that combines Suno 's signature prints with Uniqlo 's trademark ease. The best part? You can shop it now. Our favorite (at the moment) is this sweet sleeveless blouse  ($30).
How cute is the Levi's x Liberty  collaboration? Classic denim silhouettes with the timeless British floral print all rolled into one, and because it's Summer, we're leaning toward this pair of 501 Jean shorts  ($114). What about you?
The Peter Som for Anthropologie collection  hit stores May 17, bringing with it Som's expertly crafted prints and feminine silhouettes.
When Tracy Reese teamed up with Anthropologie , the designer brought her standout spin on ladylike dressing. The results are a lineup of bold-printed dresses we want to take to just about every event on our Summer calendar, starting with this Meadowscape dress  ($348).
When two of our favorite accessories designers join forces, it looks like the Tom Binns  x Charlotte Olympia  limited-edition collaboration. Timed to reflect the current Met exhibit, Punk: Chaos to Couture, the Dolly Riot, a safety-pin-accented platform pump; the Kitty Anarchy, a neon-embroidered cat flat complete with piercings and stud detailing on the heel; and the safety-pinned clear Pandora clutch make up the three-piece collection. You can shop all the styles  here — while they last!
We can barely contain our excitement at the thought of the Phillip Lim  for Target collaboration. Slated to debut Sept. 15, it has us looking forward to much of the same Lim aesthetic we know and love — all at a much lower price point. Get your sneak peek right this way .
Introducing the latest way to protect your eyes from the sun: Rachel Comey x Prism London's black sunglasses  ($357) are too cool. The matte-black frames are actually hand-carved out of blocks of acetate and finished (also by hand) in a family-run factory in Northern Italy. Got all that? If so, then you're ready to shop them now.
Karlie Kloss has teamed up with Frame Denim  and two of her friends — Jens Grede and Erik Torstensson — on a two-style capsule called Forever Karlie. The extralong jean styles not only focus on length (which is a necessity for the tall stunner), but also include a slightly higher waistband. Featuring both a skinny and flare silhouette, Karlie's collaboration will be available in select stores the first week of June.
Another shot of Karlie Kloss in the skinny Forever Karlie style, as part of her Frame Denim  collaboration campaign. Look for it the first week of June!
Starting May 15, A.P.C. and Nike  are teaming up again, releasing two styles in two different colorways. With the Dunk priced at $85 and the Air Max at $120 , it won't be hard to afford this cool-girl kick. The hardest part? Snagging a pair before they sell out (fast).

Available now, this Jo De Mer + Piamita Coco bikini  ($250) is perfect for amping up the print in your bikini collection. It's sold exclusively on Edition01's site and features Piamita's signature Tangatito print. We personally love the hot-pink halter strap for the perfect amount of color contrast.
Rachel Roy  and FEED Projects founder Lauren Bush Lauren created the FEED 100 India bag  ($78) in two different colorways. For every bag sold, 100 school meals will be provided to children in India. What more could you want? It's a great Summer tote with an even better message behind it.
For the third year in a row, J.Crew and the CFDA/Vogue Fashion Fund have teamed up to show off an emerging lineup of American designers. Starting May 22, you can shop three exclusive limited-edition collections, courtesy of 2012 CFDA/Vogue Fashion Fund winner Greg Chait, of The Elder Stateman, and runners-up Tabitha Simmons  (shoes pictured here), and Jennifer Meyer . Get a sneak peek  at the collaborations here.
Nikki Reed  — and her jewelry line Mattlin Era — designed a limited-edition five-piece collection  for 7 For All Mankind . The capsule was based on the denim label's Spring '13 collection, and features everything from earrings to bangles to one starry-spiked necklace.
Here, Nikki Reed  wears the 7FAM x Nikki Reed Humility Necklace  ($68) and the Story Telling Bangle set  ($84).
Brazilian shoe brand Melissa teamed up with Forever 21  on a summery sandal collection officially called Mel For Forever 21 . The lineup of colorful jellies includes thong styles as well as more traditional gladiator versions in slick red, navy, black, and white. Of course, the most enticing selling point may be the price, which is — in line with Forever 21 — very affordable. You can shop the collection  here and now.
Could this be one of the prettiest collaborations we've seen yet? Perhaps. Calla and Comptoir des Cotonniers  have put forth a floral-print collection that just screams "wear me to your next outdoor soiree," and we might just do that.
We gave you a sneak peek  at the Lulu Frost  for J.Crew Summer '13 collection because we've been obsessed with it since we caught wind. While the collaboration doesn't hit select stores (or online) until May 20, with prices ranging from $98 to $278, you can plan out which statement pieces will go with which outfits. Right now, we've only got eyes for this particular necklace. What about you?
In case you're looking to reinvigorate your current stock of Summer-worthy sneakers, these Bensimon <3 DKNY tennis kicks  ($65) are a perfect solution. While the turquoise and orange laceless version are great for an easier slip-on kind of wear, you can also snag a pair of the black lace-ups, too.
BaubleBar  has a knack for aligning itself with cool-girl brands, and this latest jewelry collaboration is certainly proof of it. The Luv AJ  for BaubleBar collection consists of three pieces — earrings, a bracelet, and a necklace — and prices range from $32 to $48. We're currently eyeing the pierced triangle earrings  ($32) for an edgy-meets-geometric take on accessorizing.
Soludos  has released its latest espadrille collaboration, and it's with African brand Lalesso . In effect, we're privy to bright patterns — inspired by sarongs worn by Swahili women in East Africa — and that covetable summery sole that goes with just about everything come hot weather. Take a look at all the styles here !
Sunglasses label Illesteva  has teamed up with man-about-town Waris Ahluwalia (aka House of Waris) to create a limited-edition line of eyewear that's an undeniable combination of two schools of cool aesthetics. They're priced at $250 a pair, and you can snag your own  here .
From unicorn-icon sweatshirts to bright floral bikinis to one handy mesh backpack, the Spring Breakers film has inspired an exclusive collaboration with Opening Ceremony. And this bikini has beach vacation  ($100) written all over it.
The limited-edition Giles & Brother x JewelMint  collection is what the cool girl needs in her Spring jewelry arsenal. While it's selling out quickly, we're hoping to get our hands on this multispear collar  ($60), which effectively puts a cool horn-accented spin on a brass chain necklace.
For the girlie girl, this partnership between TOMS and Shabby Chic is a sweet combo of florals and a cork wedge. And for $75, you can snag the strappy wedge , which features a soft cotton upper for extra comfort.
This is what happens when Greek designer Mary Katrantzou — and her colorful prints — teams up with denim label Current/Elliott . In effect, you've got cool jean staples in a flurry of eye-catching patterns . . . a perfect addition to your growing Spring wardrobe. With everything from cropped pant styles to flirty flared skirts to boxy tops, there's something fun for every kind of styling personality.
You may recognize these cool-girl heels from the Preen Spring '13 runway , and guess what? You wouldn't be mistaken. The London-based label teamed up with Aldo to create a lineup defined by bold pops of color and reptilian prints, all priced at $155.
Preen x Aldo Rise Musilova Heels  ($155)
Preen x Aldo Rise Pravda Pump  ($155)
Preen x Aldo Rise Pravda Pumps  ($155)
Preen x Aldo Rise Musilova Heels  ($155)
Available now, the Derek Lam for Kohl's DesigNation  collection is basically the best getaway-themed gear we could imagine. Priced at $36-$98, you'll find breezy knit tops, silky maxi skirts, bold-printed rompers, and chic long vests for layering.
Selima  Optique has joined forces with Club Monaco  to bring two vintage styles — in four colors total — and they're now available exclusively at clubmonaco.com . We're currently eyeing the Marilyn in a Summer-perfect bottle green hue  ($145).
Model Lily Aldridge partnered with Velvet on a capsule filled with apropos model off-duty pieces. For us, this Ruby army jacket  ($149) is the quintessential Spring jacket and a must have for layering.
We've got backpacks on the mind , and this Herschel Supply Co. x Madewell colorblock backpack  ($55) comes in the prettiest Spring pink-meets-coral pastel palette.
As if we couldn't sing the praises of this partnership  any more, now we've got something to zero in on: the Goldsign for J.Crew Jeane Jean  ($288) is our answer to how to achieve that boyfriend-chic look. With a more relaxed fit, lighter wash, and Americana vibe, it has t-shirt, Converse, and baseball cap styling written all over it.
We've had our eye on the low-heeled pumps  for awhile, but this Loeffler Randall x Tucker lock clutch  ($295) is our latest Spring bag must have. Print on print paired with a versatile clutch-to-chain-strap bag is ideal for a daytime outfit punch-up.
UK bauble brand Mawi has teamed with Italian heritage house Bruno Magli  on a capsule that aptly captures the sparkle and shine of warmer days ahead. We're in love with every piece — the heels! the earrings! that choker! — but we'll have to wait until late Spring for the actual release on BrunoMagli.com . Until then, we leave you with this statement piece.
Here's one way to add a little printed intrigue to your work wardrobe: the Jen Kao for Anthropologie Devi pencil skirt  ($128) is dynamic but totally chic and flattering.
We couldn't resist including a second piece from the Jen Kao  for Anthropologie  collection — formally called Mah Na Mah Na — and it just so happens to be this shakti lace kimono blouse  ($158). So sweet and feminine, but what we love most is the versatility of it. Style it over a top, as a jacket, or as the perfect complement to a floral Spring dress.
The Kate Young for Target  collection hit stores April 14, and we're loving this tuxedo-inspired jumpsuit  ($80). But if jumpsuits aren't your thing, there are more party-appropriate wares (prom dresses, too!) that might fit your personal-style bill.
These Keds x Kate Spade New York pointer sneakers  ($85) aren't at the top of the list just because of their POPSUGAR pink appeal — they're also a great way to increase your Spring color quotient tenfold.
If you're on the prowl for a limited-edition wedding  dress, the Peter Som for BHLDN  collection could be a supersleek option. In particular, the Olivia gown  ($3,000) is a perfect combination of dainty ruffles, bohemian billowyness, and one sexy fitted bodice.
Nothing says you're ready for the beach like wearing a piece from the Diane von Furstenberg x Roxy collection . Whether you're into itsy-bitsy bikinis or more practical rashguards , this collaboration offers up a little bit of everything, and at a price ($30-$90) that won't break the bank.
Stylist Cher Coulter — her clients include Kate Bosworth  and Sienna Miller  — teamed up with AG Jeans, and the result churned out quirky-cool pieces like this butterfly-print legging jean  ($225). From afar, it looks like a mod print, and up close, it's sweet and girlie. Plus, the ankle cut fits right into Spring's need for lighter, skin-revealing silhouettes.
When two Italian shoe designers come together, there's no way you can lose. Case in point: the Superga for Roberto del Carlo high-top sneaker  ($335) provides us with kicks that are sporty, chic, neutral-toned, and scallop-edged. In effect, just a very cool shoe.
Well, hello polka dots! We think the Blank NYC x Madewell skinny jeans  ($88) provide a casual way to wear one of Spring's cheekier prints.
