Be the best-dressed girl on your tennis team after a spree at this upscale athletic boutique.. In Short Deka is not your ordinary sporting goods store. These are workout duds for girls with a sense of style. This airy Buckhead boutique stocks its tennis skirts, warm-up suits and yoga togs on well-spaced racks, leaving shoppers plenty of room to move around and admire the wares. Look for upscale labels like Stella McCartney for Adidas and Christy Turlington's Nuala line for Puma. Deka also carries hard-to-find brands like Millie Fox (from England), Blue Fish (from Brazil), and Pure Lime (from Denmark).
