I purchased this from the Alo Yoga official website a few days ago at full price. I have only tried it on at home. I usually wear Lululemon leggings size 2 or 4. I think the size is about XS or S in Japanese sizes, but please use this as a reference only. I am selling this at a low price, so please be sure to accept no returns and no claims. Although it is only in a try-on condition, it is a used item that has been in someone's hands once, so please refrain from purchasing if you are nervous or if you are looking for a perfect product. Please understand that the item will be shipped in simple packaging.
