70s vintage black rainbow sequin disco festival strapless tube top pant jumpsuit

this fabulous rainbow sequin jumpsuit “made in the u.s.a” presumably from the 70s is ready for a night out at the disco! the one-piece jumpsuit is made by JC Penney Fashions (tag has been cut but was determined by research) and it has a International Ladies’ Garment Workers’ Union label (ILGWU) still attached. the garment features a tight strapless tube top bodice covered in a striped rainbow sequin pattern, and it is made of a stretchy acrylic/acetate/elastic blend that feels ribbed, and is lined (so no itch). the attached black pants have a tapered silhouette and they are made of a thin 100% polyester that is slinky, lightweight, and unlined. the jumpsuit goes on pullover style, and is pictured on model who is 5’6. size is tagged as 5-6 and I would say this best fits womens size small or medium- however, please check measurements. in great vintage condition with light signs of wear. measurements (lying flat): pit to pit (bust): 12.5-13” across (25-26” when doubled) waist: 12-12.5” across (24-25” when doubled) – but waist has stretch. the model wears 26-27” waist centre back length: 49.5” inseam: 30”
