This is a Xtra small to small in size with a max chest coverage of 34" and a hip of 39"......it has two ties on the inside to keep it pulled together, and even stilll it may show off some of your under things, just so you know.
It was very hard to get pics of on a hard mannequin, so it looks a little strange I guess with this one you just need to use your imagination......
Great vintage find!!!
This should be washed in cold water on a gentle cycle, treated with kid gloves it will last you many more years.
