This is an adult leotard from BLOCH. The size is L. I bought it this spring, but I haven't had much chance to wear it, so I'm selling it while it's still in good condition. The lace on the back is lovely and provides good coverage, so you can feel secure! The following is a quote from the Rakuten shop where I purchased it: ===================================== 【BLOCH☆Block】≪CHIWA≫ Adult Short Sleeve Leotard This is a ballet leotard from the famous brand BLOCH, which is not widely available in Japan. Lace is used boldly from the chest to the shoulders and back. Many buttons add to the stylishness! Only the top fastener can be removed, and it's easy to fasten because it's elastic. It has excellent elasticity, so it can handle any movement. Although it's short-sleeved, the chest, sleeves, and back are lace, so it's breathable and can be worn all year round♪ The see-through back gives it a mature look and makes your body line look beautiful☆ It's easy to match with your usual wrap skirts and shorts, and just by incorporating this leotard into your coordination, you'll have a glamorous impression. The chest has a lining. There is no bra cup insertion opening. When attaching a bra cup, you will need to sew it on yourself. ◆Color: Black ◆Size S size: Bust 82～87, Waist 61～66, Hips 89～94, Girth 145～150 cm, Height 152～160 cm (Flat measurement: Total length 59.5cm, Bust 30cm, Hips 31.5cm) M size: Bust 87～92, Waist 66～71, Hips 94～99, Girth 150～155 cm, Height 158～168 cm (Flat measurement: Total length 61cm, Bust 33cm, Hips 33cm) L size: Bust 92～97, Waist 72～77, Hips 99～104, Girth 155～160 cm, Height 165～176 cm (Flat measurement: Total length 63cm, Bust 34cm, Hips 36cm) *Girth: The length from the shoulder, through the crotch, and back to the original shoulder. ◆Material: 88% NYLON, 12% SPANDEX
