Leal Daccarett button up white pouf sleeve medium

Stunning blouse purchased from REAL REAL bust 34” waist 34” length 26” purchased new. Worn a couple times. The bottom button snap needs to be replaced it is a very delicate snap and it seems to have come off in dry cleaning. There appears to be very faint spots which I have taken pictures of .. cannot see unless on top of it .. super faint .. just a fabulous cotton and stylish top. Moving and cleaning closets 😌
