This is a Pi-Curve leotard. It was worn over pants and tights. Size M (110-125). It's larger than Chacott size 110. I bought other leotards as well, so I didn't wear this one for every lesson, but it has been used. Also, there is about an 8cm fray in the lace on the back of the skirt, which I sewed with a sewing machine (Photos 4 and 5). It still seems usable, so I'm putting it up for sale. Please understand that there is a fray and that it is a used item before purchasing. Size: M (110-125) Material: 90% cotton 10% polyurethane Separate fabric: 100% polyester Made in Japan
