Condition: tried on and washed but never worn, small red stain at the back (see last pic) Info: Taupe long-sleeve button-up crop top with collar and front ruching. Lightweight fabric but not see-through. 94% polyester 6% spandex. Top of shoulder to bottom hem approx 17", armpit to armpit 17". Story: Purchased from Forever 21 but didn't notice it had a stain. No clue where the stain could've come from unless it arrived like that. 🤷‍♀️ Also color is not very accurate in 4th photo, it just shows how it looks on.
