This set is so unique! The fabric is a thin satin so Madi wore nude (white would work too)bootie shorts and tube bra underneath. The pants tie in the back and the satin tube top has a spandex back so it will stretch and could fit a couple sizes bigger than Madi. Madi is an XS/S top, 27” waist, 38” hips, and she is 5’5”.
