How Chic-ago! The Best Festival Looks From Lollapalooza

When crop tops are everywhere, it was refreshing to see this bare midriff in a different style. Lauren's knot-tied maxi dress was one of our favorites – as was the way she added a mismatched Topshop necklace and sporty Oakley shades.

Dare to dress like you did in junior high! Lydia went with a vintage-like D.A.R.E. tee, some acid-wash overalls and a black leather fanny pack to bring a little nostalgia to Lollapalooza.

Umbrellas only get you so far at a festival. Abby opted for a sturdy Forever 21 hat that complimented her vintage denim shirt.

If you're going to wear shorts, try more feminine styles, like Jen's Free People playsuit – cinched with a cute white lace cardigan – and Sarah's BCBG crochet shorts with scallop trim.

Rain didn't stop Abby from wearing her beaded floral Topshop dress.

Gabriella didn't mess around when it came to footwear. Her extreme gladiator sandals elongated her legs and somehow didn't compete with her printed Intermix shorts or fringed Zara top.

Christina was all about her denim vest, which she paired with a Topshop crop top and Jeffrey Campbell flatforms.

If you have your own sense of style, don't change it just for the festival. Lydia stayed true to her retro sensibilities in a flirty dress and bold burgundy hat.

Heighlen loved how her extra-long Topshop maxi skirt made sitting in the grass a breeze at the festival.

Anyone who will wear oversized white shorts on the rainiest day of the festival isn't going to let anything stop her from having a good time. Yet, somehow Jenna made sure to keep her striped ASOS top and shorts mud-free. The only victim? Her ASOS sandals.

One of the rare Chanel sightings at Lollapalooza was this black quilted backpack.

Tedi looked beyond comfortable in this Free People t-shirt and Anthropologie maxi skirt.

Bringing a '90s vibe to Lollapalooza, Monique wore a sheer Lush shawl over a lace-trimmed Urban Outfitters top and, naturally, vintage Levi's. Her cutout Jeffrey Campbell boots offered up added edge.

Like friendship bracelets, this pair showed their love in two different colors of the same Free People dress. Jenna played up the cream dress with colored Ray-Bans, and pal Nicolina chose an Aldo bag and Target boots.

When you've got a jumpsuit, from Reformation, that makes this stylish of a showing, go neutral with accessories, like Katie did with her vintage beach bag, Toms sunglasses and shoes, and Bones & Feathers jewelry.

It's no surprise Christina Pacelli's day job is as a fashion stylist. The street style pro, in an Alexander Wang leather shirt and Alaïa skirt, accessorized with a 3.1 Phillip Lim bag, Celine shades, and mint green Topshop shoes.

Want that just-rolled-out-of-bed look? Carly took it literally when wearing this adorable romper from Anthropologie, which was actually sold as pajamas. A vintage Louis Vuitton crossbody and Old Navy sandals completed the look.

Southwestern-inspired carryalls, like this multi-colored woven backpack, were all over the festival grounds.

We thought Emily's crop top styling was so refreshing. Instead of pairing her formfitting halter crop top with equally tight shorts, she played with proportions with a pair of super-wide-leg pants.

The perfect dress to take you from Lollapalooza to dinner in the city? This coral-and-black striped one. Of course, we appreciate how Darcy dressed it down with a cool pair of combat boots.

White on white! Caitlin paired a Nasty Gal dress – over a black Urban Outfitters bralette – with a Steve Madden crossbody bag.

Perhaps our favorite strapless top of the fest, Mary's aquamarine pleated sweetheart top looked beyond comfortable.

Whitney was a vision of relaxed comfort in loose Oneil tank, Chan Luu wrap bracelets, and Toms shades.

Andie channeled the '70s with her flared pants and fringe-hemmed tank, both vintage.

A cool styling trick that also helps avoid mud splatter after a momentary festival rainstorm? Knotting the hem of your dress, like Rosemary did.

This vintage beaded crossbody bag looked as sweet as candy.

Shorts chic! Melodey opted for bold red Charlotte Russe shorts, while Maggie, in a comfy Ralph Lauren top and Toms, chose a striped J.Crew pair.

Not a hat we typically spot at an outdoor Summer music festival, but we still adored Ronna's vintage headgear.

A look cool enough for the hottest day was found on Stephanie, in crisp Joe's Jeans shorts and a white Vince top.

While backpacks are ubiquitous with Lollapalooza, we swooned over this luxe leather MCM bag.

Sure, it might not be the easiest outfit when in line for the bathrooms, but how could Molly not wear this gorgeous Anthropologie jumpsuit? Pairing the piece with a Forever 21 shawl and fringed crossbody bag, she looked perfectly at ease.

Tricia was flirty in florals in a Bebe dress and an Urban Outfitters black bucket bag.

We thought Olivia's vintage embellished tank top — with Rag & Bone booties — was sheer perfection.

The urban setting of Lollapalooza makes this decidedly urban look fit right in with the flower crowns and cutoffs. Acacia suited up in an all-black ensemble that included an ASOS leather jacket, American Apparel jeans, and Urban boots.

Perhaps the most fitting jacket of the festival, this hand-painted "Music Is the Answer" army jacket, which was designed by Jac Vanek, said it all.

A music-fest style philosophy to live by? You can't go wrong in denim cutoffs! Flora paired hers with a floral Urban Outfitters top and suede fringe sandals.

It doesn't get more all-American than with Kelly's PacSun sleeveless button-down and cuffed Sanctuary shorts. Sophia — although not rocking the red, white, and blue — had an equally fun vibe in a Forever 21 romper.

Cristin went full-on boho with her Jen's Pirate Booty dress and a turquoise Alyse Ziede statement necklace.

A true festival veteran, Alexa was prepared for any type of weather with her teal Roberto Robledo jacket and Pony high-tops.

The halter neckline of Marie's H&M crop top has been on many red carpets this season, and we love how she paired it with a black-and-white printed Kohl's maxi skirt.

Besides embracing the requisite floral crown, Yasmine got into the festival spirit in a revealing fringe top and vintage YSL sunglasses.

With so many loose floral dresses at Lollapalooza this year, Katy set hers apart with a flouncy Forever 21 hat and a slouchy H&M bag.

One of the more girlie looks came from Katie, in a white chiffon skirt with a matching fedora.

Crop that top! Kendra wore a fitted American Apparel crop top over her Skylark pants, while her well-coordinated pal Jac wore hers with a sheer black Urban Outfitters skirt and a leather jacket.

When you opt for a monochromatic outfit, why not pile on the jewelry? These layers of silver necklaces from Aldo added an edgy vibe to a basic black top.

If you want a look with coverage that's still supersexy, try Cristina's sheer floral Nasty Gal top, which she paired with black Urban Outfitters shorts and a Coach crossbody minibag.

Neutrals were a smart move for these friends when it comes to effortless looks that transition from the festival to the city. They had the minimalist look down, from Amy's checked H&M shawl to Melissa's J.Crew dress to Alannah's black Gap jeans (with a pop of color with mirrored blue Ray-Bans).

Overalls made a big comeback on the festival circuit, and Lauren's American Eagle ones were the perfect mix of comfort and style — as were her accessories, a Rebecca Minkoff bag and studded Frye boots.

While some opt for loose-fitting clothes for a full day at the festival, Ange brought her A game in a body-con dress but dressed it down with a flannel shirt and fringe boots.
