I used to, years ago- But then stopped going for some reason. I just sorta forgot about them over the years. But I recently rediscovered this passion. There are a few good consignment shops in Dallas. I'll tell you about one in particular today... Rethreads!
Rethreads has both women's and men's clothing. Tons of great designer labels, gently worn by other people first. What you save in price makes the hand-me-down idea oh-so-acceptable!
On a recent visit, I got this sweater, by Alberto Makali. It was priced in the store for $45, but everything in the store that day was an additional 20% off because it was the first weekend of the month! (That's your additional Thrifty Thursday tip!) So I got it for a grand total of $36. I don't really know how much it would have cost me if I bought it new, but I can tell you, it'd be too much for me to feel happy about, and so I never would even buy it.
