Ever wish you'd kept all those dorky iron-on T-shirts you wore as a kid? If so, get a load of Sugar. Nestled among the vintage shops on Broadway, the year-and-a-half-old boutique has a huge selection of retro-'70s and '80s iron-on transfers -- as well as custom lettering -- that can be applied to the shirt of your choice in minutes. Fancy unicorns? Atari? Joan Jett? They've got it. Sugar also carries a modest but unique array of men's and women's retro attire, jewelry and accessories. Sweet!
