ome Back Bay boutiques make you feel you're not worthy of the salesperson's valuable time. But five minutes in the low-key Uncle Pete's will make you feel more like you're at a friend's house than on a shopping mission. The men's and women's clothing and accessories are displayed in a showroom that's spread out, uncrowded, and low key. It's also stylish as hell. All of the fixtures, including the illuminated Uncle Pete's sign, were selected or hand-made by a former set designer for Disney and Uncle Pete's carries fiercely independent brands including Vena Cava, Under.ligne, Rag & Bone, and, for men, Simon Miller jeans, CDG, and YMC.
