This is a NIKE sports bra! I used it a few times, but then I got pregnant and had a baby, so I lost the opportunity to exercise and decided to sell it! It has hooks on the shoulders and under the bust, and the shoulder straps are adjustable in length ⭐︎ There are no noticeable stains, but please understand that this is a personal inspection. If you have any questions, please feel free to comment＾＾
