NOT-SO-BURIED TREASURES: When was the last time you stopped in to Buffalo Exchange? It had been a while for us, so image our surprise when a visit this week revealed racks packed with more famous names than we’ve ever seen at the green-minded resale boutique. “Hello, Betsey,” we purred as we shopped. Or, “So good to see you again, Ms. Malandrino.” A peek at the denim selection also netted blues from the likes of 7 For All Mankind and more – all at bargain prices. Who knows what you’ll find? Happy Hunting! GET IT: Buffalo Exchange, 3424 Greenville Ave., Dallas, 214-826-7544.
