In addition to being astonishingly shiny, the brand new Cosmopolitan resort/hotel/multimillion-dollar den of iniquity offers an actually rare shopping experience for seasoned Las Vegans. Rather than building yet another shrine to designer egos, The Cosmopolitan has taken a unique approach to shopping in the form of a series of multi-brand boutiques. These well-curated shops offer tightly edited selections of labels that can be hard to find even in the Strip's most cavernous department stores. We're the most excited about DNA2050, a high-end denim shop offering cult favorite lines such as PRPS, Edwin, and Stitch's, and Beckley, a women's boutique that offers dresses from coveted Australian line Lover and tough-girl jewels from Fallon and Iosselliani. And don't miss UK import AllSaints Spitalfields. This London institution has been keeping British women and men in their particular brand of well-made, vaguely post-apocalyptic togs for ages, and with this location, the U.S. onslaught is on. Get into it before everyone else does. The Cosmopolitan, 3708 Las Vegas Boulevard S.
