The price of fashion takes its toll in many ways other than the slimming of that designer pocketbook of yours. "Chic" eternally revolves and recycles in a vicious, cannibalistic circle, and the constant struggle to remain in The Now seems all but insurmountable when everything ends up being (or actually strives to be) so five-minutes-ago. Short of taking a not-so-scenic thrift-store tour of North Texas--one that's decidedly more famine than feast--the options for the frugal fashionista have been limited, but the chain known as Buffalo Exchange succeeds in both remaking and remodeling even the most discriminating wardrobes. Set up in much the same way as a used record or book shop, BE specializes in the buy/sell/trade of threads that have worn out their welcome, without the hassle of sifting through shop-class ashtrays and incomplete Sesame Street puzzles. Be it the latest trends in street wear, a reinforcement of the tried and true or the funkiest of vintage statements, the clean Greenville Avenue outlet has a consistently organized and shifting stock, and it's quickly become an essential weekend stop.
