I'm not much of a fashionista or even one to peruse much of the thrifty stores in town, but when found in Plaza on a Saturday, Hong Kong is a typical stop. The owner and all of the staff are very welcoming and always offer to help you find what you're looking for (if anything).
There's plenty of killer selections of plaid, vintage, odd graphic tees, boots, leather jackets, and 60's/70's decor/kitchen items. I saw some cups last time I visited and was tempted to pick them up for the simple and obvious 70's-style patterns. Pretty far out, maaaaan.
I've picked up several t-shirts from here and love the wear on them. Found some great baseball henleys and a few kick-around shirts. Prices can vary depending on what kind of "find" it is in the vintage world.
All around a cool spot and a destination if you're into the vintage scene in Crown Town.
