A vintage 1970s deadstock denim jumpsuit. The jumpsuit is halter style with wide legs, front hip pockets, and a back metal zipper. The maker is "March 1", and the denim is a cotton/poly blend (67% cotton and 33% poly).
Bust: has some flexibility because of halter style, but I'm guessing the max bust is around 36"
Bodice length has flexibility because of ties at back neck
Leg length: 43"
Rise: 13" in front, 14.5" in back
Inseam length: 32"
Condition: Excellent. Deadstock. I haven't washed it because it still has its original tags (but there are no stains or spots).
