Incredible vintage dream coat like dress

Seriously.. this is even more gorgeous in person, it’s a living dream Colors, textures, stitching.. the flex of light it captures .. it’s pure magic Length ~ 56 inches Armpit~ 9 inches Pit to pit~ 27 Sleeve ~ 23 1/2 inches Neck across ~ 7 inches (slit in front give plenty of room for head/hair to fit thro easily) There are no tags, might be hand made (it appears that way to me) I put for size M , but with measurements I supplied, I would think comfortably a small medium large would be perfectly fine
