As mentioned by other reviewers, this product rubs under your arms. I even extended the staps so it would sit lower, but the product rides up with movement, so there is no way to avoid it. If you only wear it for a couple hours, it might be tolerable, but after wearing it once, I'll never wear it again. It only provides light shaping and is made of the satiny spandex. Great seller, with fast Prime shipping, but product was a fail.
