Contour Squareneck Longsleeve Bodysuit A cult classic for a reason. This is a squareneck longsleeve bodysuit with a thong-cut bottom and double-layer fabric for a supportive fit. It’s made with Contour — luxe, ultra-flattering fabric coveted for its smoothing effect and second-skin feel. Nothing more essential. Hidden Hold Loops keep your bra straps in place and out of sight.
