This very unique medieval style top is beautiful and very witchy-poo with huge bell sleeves. It is light weight, yet velvety with beautiful beaded emboridery along the bodice and empire waist. There is no back support to keep the shoulders up, so it must be a tight fit. I have two of these, one is marked a small, and the other a medium, but the measurements are much more for an XS and a S, so they must be junior sizes. That would make the small a misses XS and the medium a small. The bust measurement is anywhere from 32" to possibly 34" stretched for the small, and the medium is about a 34" bust to possibly a 35 or 36". Lying flat armpit to armpit was 16" for the small and 17" for the medium, but since there's no back to the top, this measurement is difficult to take. The empire waistline just under the bust is about 12-15" laying flat for the small, and about 13.5 for the medium. I've sold several of these tops through the years and have never had anyone complain about them, so it should work out if you know your measurements. The tops do have some stretch to them and are designed to be form-fitting. The length for the XS is about 28", and about 29" for the small, but this can easily be controlled since the sides are entirely ruched. They are brand new without tags.
