(That's booty as in pirates, not as in J-Lo).
We don't really have thrift stores as such in this country, we don't have estate sales, and yard sales don't exist either. What we do have is the Great British Car Boot Sale! We have quite a good one near us, at Ford, and there's always good stuff there. The downside is that the vendors are usually pretty clued-up, so prices are quite high, but there's still usually a bargain to be had. That's my sister in the picture, rummaging for sewing notions.
I came home with a dress, a jacket, a 1940s silk blouse, an adorable set of folding travel hangers, and a selection of vintage hankies and collars. Result!
