Vintage 1980s Black Sleeveless Jumpsuit, A. Byer Size Small-Medium, Tapered Leg

Black cotton sleeveless jumpsuit from the 80s. It does not have any openings and the fabric does not stretch (except for the rib knit triangle in the bodice) so keep that in mind when checking the measurements. There are belt loops on both sides but no belt.  *The belt in the photos is not included* Brand - A. Byer California Content -100% Cotton, Rib inserts are 50% Cotton 50% Polyester Size - Labeled Size Large but I think it's better for a modern Small-Medium so please check all measurements to ensure fit.  Chest - 18" pit to pit but it has a tiny bit of stretch beacause of the ribbed insert Waist - approximately 18.5" across Hips - approximately 19.75" across Inseam - 27.5" Thigh - 12.25" across Leg Opening - 5.5" across Shoulder to Hem - 54" Shoulder to Crotch - 30.5" Condition - It's faded but maybe that was the original look?
