I am selling this item because I didn't feel much effect. I wore it for about a month. I wore it over my undershirt. I purchased it from a retailer. This is the magic shirt that appeared on the popular YouTube show "Reiwa no Tora" (Tigers of Reiwa). The sizes are for women: Shirt: WL Spats: LL Pants: L-LL There are no noticeable stains, and I think the back is fine, but there are a few small pills due to several washes. Please understand. Please check the condition in the photos. If you need more photos, please comment. -------------------------------------------------- [Patent-pending] This magic shirt draws out your natural physical functions just by wearing it, improving muscle strength and flexibility.
