Lizzy & Johnny vintage 70's black disco sequin jumpsuit Studio 54 size 8

100% polyester. No snags or flaws in the vintage fabric. size 8 but waist measures 11 inches across at the smallest part and there is not much stretch. I feel this fits more like a modern 6 or 4. I am 5'2" 140lbs and it is too snug. inseam 26"
