My sister and I collected and wore these vintage clothes in the late 1970s through the 1980s. At the time all of the thrift stores sold clothing from the 1940s and 1950s frequently, so we amassed quite a few. We are both large girls (I was 5'9" and about 130 lbs) so these clothes should fit girls who are size 8 to 12.
Sorry, we wore these clothes as daily work wear (many times with Fifties stiltto heels!), so they have seen wear. I have very fond memories of a lot of these clothes, and loved wearing them.
