Express drape top

This party silky drape top is new with tags and ready to go out as soon as we can. It silky. Has the tiny spot on the strap at the neck. I don’t know how it got there. No have never tried to remove it as the top has never been worn. Still has tags it’s from the express. Bought it for a club, wore the other top I bought! Also tiny maybe snag. Included it photos. Please ask any questions or request more pictures if needed.
