Vintage tank top

Super cute and in great condition! This shirt was found in a trunk in my mom’s attic. Guessing from the 1970’s or early 1980’s. Has button shoulder straps and an elastic waistband. Flowers all on the front of it with a small line of flowers on the bottom hem in the back of it. Pleats are along the front @ back necklines. I’d keep it myself if it fit! Says size “E 11” but I’m going to guess it’s along a size Small. Measurements are here: Armpit to armpit = 19” Mid shoulder to bottom hem = 21” Other measurements upon request.
