I weigh about 190lbs and usually wear a 1X, but the first one I purchased was so tight, I exchanged it for a 2X which fits perfectly... I feel good in it, and sit for most of the day and it doesn’t pinch or hurt. It looks really nice with slacks and skirts, lift the butt. One thing I love about shapewear is the return policy... I recommend anyone to purchase from this site and purchase this body suit.
