Vintage "LMD" mini dress, EUC, SMALL

Vintage "LMD"mod mini dress, size small. Sleeveless, orange with overlay of lace, cut out flowers. Lined, hook & eye, zip close. Fabric: I am guessing that it is some polyester blend. Measurements (approximately): neck (all around)= 24, chest (flat)= 16", arm hole (all around)= 19", waist (flat)= 15", hips (flat, 5" inches down from waist)=.17", front and back length (from shoulder to bottom)= 32". .Concerning size, I bought this dress on PM. It has no inside tags (except for brand name) but was listed as a medium. I am a size 8 and this dress was skin tight on me! Therefore the size is definitely a small or even an extra small. I will add that I absolutely LOVE this dress. I was very disappointed that it did not fit. Thanks for stopping by!
