Vintage Dorsay red slip dress

Hello! This is such a beautiful piece with a scalloped hem, lace trim and adjustable straps. No material tag, nylon? Size is average 34- looks like a size small. Will list under 34B. Please see measurements. Amazing condition considering its age, from what I saw this is from the 1950’s. (Please do own research though to verify :) Very small snag to underside of right “V” chest line and a few very small dark dots. Last 6 pics show flaws. 2 dots on right breast and one on the back upper left. Kinda hard to see the front dots unless you’re looking for them. Please message with questions. Thanks! Thanks!
