Neiman Marcus-owned Cusp opened its first few boutiques last year to attract younger shoppers. In fact, my Nicole Richie interview was held at the LA boutique. With Cusp.com, girls who don't have a store near them can shop online any time. Offerings include party frocks, trendy jeans, fabulous shoes, and It bags by the likes of See by Chloe, Lauren Merkin, and more. There is also a generous sale section, so get to know Cusp if you haven't already.
