Off-white Sandro Paris vest tank

Very light and breezy, was on for consignment for $399, expensive brand. Unsure the material it’s made out of (tag appears cut) but feels like a cotton/silk blend. Would be great for summer or travelling in hot/humid places. Very loose and flowy, would fit a variety of sizes Very “peasant core” or “cottage core” Small stain on the upper back I think would be resolved with a run through with bleach - or whole shirt could be dyed (what i will be doing if this doesn’t sell).
