Vintage disco top. Fits like a M/L

Vintage disco top. Company “Visions” Late 70s, early 80s Rainbow iridescence makes this shirts colour change depending on the angle It’s semi sheer, tho you can’t really see thru it. Stretchy fabric that is flowy & drapey Lightweight Boxy fit Button enclosure on back neck Side slits I typically wear a small/med and this top fits me very well. Love it but never wear it. No size tag. Would guess this is a med/l. Please see all measurements to ensure fit No material tag, but this is a polyester for sure. VGUC with little signs of wear
