I purchased this at GAP. I am selling it because I have no opportunity to wear it. Size M Length: Approximately 73cm Width (from armpit): Approximately 53.5cm I have only tried it on, but it has been stored at home, so please refrain from purchasing if you are nervous about used items. There are no tags. I will fold it up small and compress it for shipping. Please understand. No claims and no returns, please. Thank you.
