Secret confession: We hardly ever buy new clothes. Why would we when there are so many like-new castoffs on the racks at Salvation Army? OK, yes, you will have to sift through many stained gimme T-shirts to get to the good stuff, but if you have the stamina, you will be rewarded with top-notch designer items from Carmen Marc Valvo, Betsey Johnson, Escada and Elie Tahari (no promises, but we've found all those labels) and scads of quality mall brands such as Anthropologie and Banana Republic. Here's another secret: Go on Wednesdays, when all clothes are half off the marked price. Do the circuit (there are seven Salvation Army thrift stores in Dallas County), but start with the huge store at Harry Hines and Inwood. You can thank us when you have a whole new wardrobe by this time next week.
