Best product of its kind! It trains your muscles & provides excellent support & after getting used to wearing it, it can easily be worn under clothing all day or night without discomfort. It supported me even during a rigorous workout in the gym lasting 2-3hrs through aerobic activities as well as weight training. Under evening dresses it gives the curves women look for to attain that beautiful hourglass shape. Choose the sizes according to your measurements & as you reshape your waistline, you may try ordering the next size down for an even lovelier shape!
