Sandwich artists, successful novelists, and Clarissa Darling all know that the best things come in layers. Stock up on an artful assemblage with today's Groupon: for $30, you get $60 worth of designer fashions at BuyDefinition, a South Congress Avenue shop specializing in of-the-moment looks and hard-to-find labels. This Groupon must be redeemed for in-store purchases only.

BuyDefinition's owner (and University of Texas graduate) Esti Choi focuses on stocking her shop's industrial space with a well-edited inventory of rare, highly coveted women's apparel, accessories, and shoes. As such, shoppers can spend hours browsing racks stuffed with rock-festival tanks, colorful silk chain necklaces, and cutesy sailor rompers. Steal the attention away from aggressive ants at summer picnics in a Dear Creatures Café Romper ($116) or cool off in a demure Samantha Pleet romper ($154). A BD Vintage Lenore lace mini-dress nails a sexy goth look in time to audition for the role of Tim Burton's girlfriend, while a Grey Antics paper-knit cardigan spares you the hassle of crawling inside a dead tauntaun on chilly summer nights. Beach bodies with more vintage proportions, meanwhile, can rock a Betty Grable pin-up pose with a '60s-style Desiree one-piece ($52) or look like the world's hottest art thief while wrapped in a watercolor, empire-waisted Camille mini caftan ($72).

Fashionable finery is like a priceless artifact—one of a kind, hunted relentlessly by those in the know, and typically housed in booby-trapped jungle temples. The sartorially adventurous, immortals of cool, and the just plain buy-curious will all find a flattering designer frock with today's Groupon to BuyDefinition.
