I love shopping for vintage clothing and accessories. And while Red Rose isn't the largest, it has the best selection of authentic vintage gear, in my opinion.
Amazing shoes and handbags, as well as brooches and jewelry for costume or going out can be found in abundance here.
The clothing is hit or miss...a lot depends on your size and what you are looking for. But even if you don't hit the jackpot, you'll have a blast shopping for it.
