VTG 80s Betsy's Things Blue Gray Striped Dress Size 3/4

Questions? Leave a comment below! super fun vintage dress from the 80s...it's got an awesome "9 to 5" vibe. this dress is probably an acetate nylon, there is no material tag. it features blue and gray stripes running in different directions on different parts of the dress. it has a very light gray, wide tie sash belt, elastic at waist (under belt), knee length skirt, 3/4 length sleeves with buttons at cuff, slightly puffed, lightly padded, shoulders, and buttons on the left shoulder. on first glance this dress looks flawless, but there are a few little condition issues, there is a small spot on the sash, a few tiny flaws with runs on the back of the skirt, and some loose stitching along the arm on one sleeve (there is another layer of stitches so it's more cosmetic, there are no holes). these are all issues you really have to look for, actually pretty minor! Please see pics. this dress is labeled as a 3/4, which seems about right, but vintage sizing is unpredictable, please see the measurements below. somehow this dress is simple but quite sensational, all at once! Approximate flat lay measurements chest, armpit to armpit 17.5" length, shoulder to hem 42" sleeve, shoulder to cuff 18.5"
