The Buffalo Exchange is awesome and I just love shopping there for cheap, designer denim and vintage Ts. If you are planning on updating your wardrobe and trading in your used clothing then make sure that it is seasonally-appropriate (no bikinis in December) and that it is fashionable. The latest Ann Taylor collections (or those that are a few seasons old) might look awesome to professionals, but they are usually shunned by the buyers at the Buffalo Exchange. Take them to My Sister's Closet, where they stand a chance of selling.
