Sadly, it's been years since we had a summer love, so this season we're determined to find a worthy crush. This time around it won't be the cute lifeguard at the beach or the yummy guy in Cabin 10, but instead, we're loving some particularly covetable must-haves! From a hardcover museum book we can't wait to flip through to a genius collaboration between several of our favorite labels, we're crazy about all the items in this month's Hearts roundup, and hope you'll get caught up in the romance, too!Sultra Hair Palette Color Hair Mascara ($24) in Capri Coral
One of the best perks of our job is testing out brand new products before they even hit the market, which is why you may have caught several WWW editors trying out Sultra's hair mascara back in April. We liked the temporary hair color so much, we decided to feature the fun coral hue in this month's Hearts story! If you're eager to switch up your usual 'do, simply swipe the mascara-like wand through your tresses for a bold pop of color. The mascara will be available online and in stores on June 28th in three other shades as well (Ultra Pink, Lapis Blue, and Royal Violet), so make sure to check it out then!

Summer Socks
Sporting socks with your high heels may seem counterintuitive, but after glimpsing this cute pairing on Marni's S/S 12 runway (the label's sling-back Shoes ($990) teamed with nylon Socks ($60) in Macaroon), we're sold on the look! The key to nabbing the same cute-meets-chic vibe is finding an understated pair of ankle socks, such as Happy Socks' Ankle Socks 03 ($10), and wearing them with a chunky, strappy heel. Toss on your favorite sundress, and you'll have a playful ensemble perfect for all your summer soirees.

Lena Dunham
Ever since we watched the clever indie film Tiny Furniture, we've had a soft spot for the flick's main star (as well as its writer and director), Lena Dunham. Now that she's gone and created our new favorite series, HBO's Girls, we're absolutely smitten with her! The addictively witty show, which Dunham produces, directs, writes, and stars in, explores the lives of twenty-somethings living in Brooklyn and struggling to figure out their lives. In real life, the talented 26-year-old Dunham is enjoying a streak of hard-won success: she's already collaborated with Hollywood heavy-hitter Judd Apatow on Girls and will star in his comedy, This Is 40, later this year. Now this is one crush that's sure to last after summer's over!

Zimmermann x Shopbop Avery Rash Guard Top ($195)
If you're a surfer girl, Zimmermann's chic rash guard--which is part of a capsule collection available exclusively at Shopbop--will have you hanging ten in no time! But even if you prefer sticking close to shore (and just watching cute surfer boys from afar), the top's high neckline and nylon fabrication serve to protect you from the sun. Unlike typical logo-heavy rash guards, this one comes in a lively tropical bird print that makes it as fashionable as it is functional!

Schiaparelli & Prada: Impossible Conversations ($45)
In honor of their lauded exhibition Schiaparelli & Prada: Impossible Conversations, the Metropolitan Museum of Art has released a companion book brimming with gorgeous photographs. The hardcover tome not only makes a lovely addition to your coffee table, but it also serves as a great conversation starter, particularly if your visitors are interested in discussing two of the greatest female Italian designers of all time!

Creatures of the Wind x J.Crew Collaboration
We're thrilled that J.Crew chose to team up with Creatures of the Wind, a young label that's already earning accolades in the fashion industry (designers Shane Gabier and Chris Peters scored a runner-up prize in 2011's prestigious CFDA/Vogue Fashion Fund Awards). The collab, available now for pre-order online and in stores June 14th, mixes Creatures of the Wind's signature quirky aesthetic with J.Crew's classic silhouettes. We think adventurous stylesetters will love the color-blocked cardigan and tee set, as well as a pair of crazy-cool oxfords!--Tiffany Tse
