Buffalo Exchange

For more than 30 years, this colorful, in every sense of the word, has been a place to shop for trendy pre-loved fashions in Haight-Ashbury. (Locals also line up regularly to sell and trade their style haul.) What you'll find: crowded men's and women's racks hanging with crazy-affordable denim, jackets, flannels, tees and dresses. Pairs upon pairs of glorious shoes are also worth a peruse. And should you find yourself in need of  purchasing a warm layer, hat or scarf (damn you, Karl the Fog) while roaming the famous street for signs of its hippie history, bet on Buffalo. There's another location in the Mission.
