The product description states that it runs on the smaller side and their sizing chart is pretty accurate. However, the fit was not my problem, it was the smell!! The material its made of has an foul odor resembling a fishy smell. I thought maybe it was the packaging so I let it air out for a few days all to no avail. The smell never went away. I ended up having to return it and search for a new corset for the Renaissance Faire.
