This is a jumpsuit/coverall made in the USA using DuPont's Dacron material. I purchased it as a vintage item from the 1940s to 1950s. It uses an IDEAL zipper. The belt buckle is also great. There are many stains, dirt, tears, and loose threads in the quilting, but it has a huge impact. The dot button on the chin strap was broken, so I replaced it with another one. The zipper on the left leg can be opened from both the top and bottom, but it's a little stiff when opening from the bottom. It can be opened and closed. The other zippers open and close smoothly. There are dot button studs around the neck, which seem to be for attaching a hood or boa, but they are not present. One of the studs is missing. Size: The chin strap is on the right front, so it's likely a women's L, 14-16. It feels like a slightly larger size than a Japanese men's M. Actual measurements: Shoulder width: approx. 47cm Body width: approx. 60cm Waist: approx. 47cm Length (from collar to crotch): approx. 90cm Inseam: approx. 71cm Hem width: approx. 22cm Thigh width: approx. 39cm Sleeve length: approx. 61cm All measurements are taken on the back and laid flat. Please consider these as a guide as they are amateur measurements. It will be folded and packed small.
