True XS My mannequin is 34” bust 26” waist 35.5 “ hip and the dress was a little snug going on. So I suggest buying if you are no more than or smaller than these measurements . It’s slips over head. No zippers. Elasticized at the waist. About 55” long. Not like new but still a lot of life left in it. No stains or snags or pills. Love this dress. So easy and great with sneakers or sandals. Or barefoot :-)
