Bodysuits cover from bust to thigh and some styles extend down the thighs. They are a great shapewear option for all-over trimming and slimming. Plus size bodysuits are usually constructed with built-in underwire or seamed cup bras. Some styles have molded cups for added support. Plus size shapewear bodysuits use compression in various levels of control. Some models have two layers--a strong mesh lining for shaping and a smooth outer layer, so that clothes glide on effortlessly. Some shapewear has a split crotch for extra convenience. Most shapewear brands have plus sizes up to 3XL, comparable to a 28 dress size or 54"" bust.
