I find Ragstock a great place to find the basics for layering. Plain short and long sleeve tees and tank tops in every color you could think of. Ragstock is always my first Halloween costume shop stop — cheap and not your cheaply made, thin, over priced costume in the bag. A dozen girls and I are running a Halloween 5k this year in 80s workout attire and Ragstock was the jackpot for this. Rad!
