I've had this since I bought it, but I never wore it, and it's been in my closet! I missed my chance to wear it, so I hope someone else will! The size is 1, which is a Small. The fabric is sturdy, so you can wear it on its own when exercising. It's unused, although the tag is missing. It's clean, but it's been stored at home, so please refrain from purchasing if you are overly concerned about this. Thank you for looking.
