Worn as an inner layer for short-sleeved or three-quarter-sleeved tops. I've added plenty of sleeves made from burgundy sequin fabric to a commercially available stretch leotard. Short-sleeved tops and no-sew tops that didn't get much wear have been completely transformed into eye-catching tops. Image ② shows an example of how it's worn with a short-sleeved top. The inner layer is size S, but it's stretchy, so it will also fit a size M.
