i personally do, you can find the nicest stuff there, and heaps of vintage things (which i love) i especially love pearls and stuff there, which is great becuase they are unique and everything there is excellent!
I used to be a bit apprehensive of thriftstores, but now I think they are wonderful - I could devote an entire weekend going to the 'cool' suburbs to visit their local second hand stores.
op shops are the best for vintage clothes and espesh accesories alot of op shops dont supply designers but thats the fun of it all the challenge to find something really cool and vintage and make it your own today
