Warehouse jumpsuit play suit. Size label S but being stretchy I would say it fits a size 12 better or even a size 14.
I wore this to a tropical 1940s Hawaiian event with hula garlands. It was very fetching and comfortable. Pullover closure, no zips, buttons. Wide-leg trousers. Elastane and polyester blend. Easy to wear. Multicoloured fabric. IT IS NOT AN ORIGINAL 1940s or 1950s JUMPSUIT.
