I don’t know what you would call this. This is my daughter modeling this one piece jumpsuit/pantsuit thing. The legs are incredibly wide. The seams are unfinished. There’s no tags or labels but one lot tag. I don’t know what the fabric is but it’s heavy and kind of silky and would burn very easily while ironing if you weren’t careful. I can’t tell if the buttons are metal or plastic, but I suspect they’re plastic. No shoulder pads. It just buttons up the front, no other buttons or zippers. Thanks for your help!
I would date it to the early 1970s. I would call it a jumpsuit since it's one piece. Your daughter is a great model!
