I bought a really cool vintage beaded clutch purse (above left) from this Etsy store over the summer, and was not only thrilled with my inexpensive (only $20!) yet glamorous purchase, but with the customer service from the seller.
In Cold Storage has an eclectic assortment of vintage finds, with my current favorite being this Mad Men-style 1960s handbag, (above right.) They also feature snappy product descriptions and excellent photos!
