Vintage 80's Cabrais Cotton Candy Pastel Button Down Collared Shirt

A Cabrias button-down from the 80's/early 90's in light and ary pastel stripes that comes straight from my aunt's closet - a true vintage find! Some buttons have been replaced giving it an eclectic look and there are some light stains on the front near the bottom edge (see picture). They are difficult to see and unclear if they will wash out. It's a S/M - oversized on a S and more fitted on an M.
