I purchased a set of pelvic support belt & compression socks here, but I'm not using these spats, so I'm offering them to someone who needs them. The following is the product description at the time of purchase: ・Pigeon Maternity Spats with Pelvic Support Size: M These are spats you can wear directly, but I was wearing them after putting on my underwear. I used these spats almost every time after I entered the stable period of my pregnancy. Please refrain from purchasing if you are overly concerned about details. Please consider purchasing after understanding and accepting that these are used items. - Size: M - Material: 95% cotton, 5% polyurethane - Design: Gray, High-waisted - Intended Use: For maternity
