This is an open-neck, French-sleeve leotard. The size is S, but the material is very soft and stretchy, so I usually wear M, but I wear S in this one. The seam on the left side is open, which was the case when I bought it, and it seems to be a manufacturing issue based on the inside (images 15 and 16). Images 17 and 18 are from Fairy.
