If St. Tropez and Palm Beach magically combined, we imagine the official uniform would be Milly's Cabana Collection. When we want super feminine, colorful beachwear, New York designer Michelle Smith consistently delivers, with her spring '10 offerings consisting of the same preppy-elegant pieces that have made her a staple in summer-towns from coast to coast. Well, if you're looking to add to your summer swim-wear essentials, you just got lucky—we just caught wind of the Milly Cabana Giveaway Contest, where one lucky gal can score $1200 of Cabana swag. There's a paisley bikini, a head-turning beach blanket, a lacy tunic cover-up, and of course, an oversized beach bag to tote it all up in. To win, just go to Milly's Facebook page and enter. But, there are no sore losers here! All Refinery readers are getting an exclusive offer from this beach-babe: 20% off all Cabana collections on her e-commerce site through July 5!
