This is a dance outfit for kids. It's a top and bottom set. I bought it online for a school sports day dance, and I only wore the pants once. The top is unused. The size is listed as 150, but it runs small, so I think it's closer to a 140. ----The following is the product description from the online store---- Waist is fully elastic (narrow). The pattern of the waist string is different for each item. Wide elastic is used to prevent slippage during vigorous movements. Please note that the waist is designed to be narrow. Side pockets included. Made in China. Please be aware that the construction is more approximate than Japanese-made items, so there may be slight stains or sewing discrepancies. Also, the sizes are slightly smaller than Japanese sizes. Please check the size chart. The tags are not in Japanese. ・Search keywords: kids, junior, children, girls, boys, dance pants, kids dance, jersey ・Available color: Red ・Available size: 150cm (I think it's about 140cm) Size/Waist/Total Length/Inseam// 150/46〜/85/61// /Jersey fabric -------------------------------- It's in very clean condition, but there may be some oversights due to my personal storage. Also, I will be sending it after covering up the name on the tag. I would appreciate it if you could understand that this is a used item.
