Joseph Ribkoff Unique Black Top w/ Mesh Sleeves

Gorgeous black top with mesh above the bustline and mesh sleeves. Pristine condition. According to Joseph Ribkoff size chart, top is a size 4. Approximate measurements are as follows: armpit to armpit - 16”; waist - 15”; hips - 17”; length - 24”. Top does have a lot of stretch and will stretch an additional 2-4”. I would estimate the top would fit a size XS or S.
