Small evening purse

A navy blue evening bag with a gold chain and a gold decorative clasp. Little design on the front. Strap/chain can be removed. It was my grandma's and she's had it for a while and doesn't remember much about it but gave a guess to what she paid for it (knowing the brands and prices she usually pays for a bag) - it may be vintage, I'm really not sure and cannot find any brand name or anything on it. Sorry for lack on info this time. 😅
