Rachel Zoe

Warm weather from coast to coast brought a lot of skin-baring styles this week, from short shorts to peek-a-boo dresses. Maria Sharapova worked short black shorts with a hibiscus-print Lisa Ho blazer in London, Malin Akerman showed a little leg in a coral Cushnie et Ochs maxi and two-tone Tibi sandals in Hollywood, Rachel Zoe went earthy in a beige National LTD maxi and statement accessories in LA, while Carey Mulligan, Michelle Williams, and Sienna Miller sported noteworthy ensembles of their own. Get a closer look at this week's winners, then shop their looks — including a few exact pieces — for yourself.

Rachel Zoe hit the beach in Malibu on Saturday with her little guy, Skyler Berman. She covered up her swimsuit with a black maxi dress, and chased her adorable Skyler into the waves. Also along for the fun was Rachel's good pal and makeup artist Joey Maalouf. Later that evening, the fun continued for Rachel. She had a ladies' night at the Malibu Inn with her pals Ali Froley and Kelly Sawyer, and shared a picture of their good times on Twitter. Yesterday, Rachel and Skyler were back out on the town to run errands together. Rachel, Skyler, and dad Rodger Berman have been all about their West Coast fun since wrapping up a family vacation in the Hamptons.

Just like you and I, celebrities showed off their patriotic Summer style during the Fourth of July holiday yesterday. Alessandra Ambrosio sported a Wildfox Couture star sweater, Rachel Zoe looked chic in a black maxi and fedora, while Jessica Alba donned blue trousers with colorblock Rebecca Minkoff sandals for the occasion. Check out 5 fabulous celebrity outfits from Fourth of July and mimic them all Summer long.

Rachel Zoe enjoyed a special stroll with son Skyler Berman yesterday in LA. Rachel and Skyler are easing back into their busy weekday routine after returning from a recent trip to the East Coast. Sklyer's been showing off his walking skills lately, and yesterday he was happy to lead the way for his well-dressed mom, Rachel.

Rachel and Skyler grabbed a bite to eat then continued on to her offices, where they met up with Rodger Berman. Rachel, Skyler, and Rodger threw a party for staffers, complete with two cakes! The day seemed to be full of happy and bittersweet moments for Rachel and her staff, as they also wished farewell to Skyler's nanny, Rusty.

Summer is the perfect time to experiment with hats. Fedoras, floppy styles, bucket hats, bowlers — the style possibilities are plentiful, and there are also plenty of celebrity inspirations to take advantage of. We particularly love how Emma Stone jazzed up her chambray shirtdress with a wide-brimmed hat, the way Kristen Bell completed her concert cool with a white fedora, and how Rachel Zoe looked '70s chic via a fabulous floppy hat. There are way more stars who have worn stylish hats, so first check them all out, then shop your favorites to add the perfect finishing touch to all your Summer ensembles.
