Vintage 1970s 1980s Teddi Sleeveless Top

Darling vintage 1970s blouse top in ivory. Sleeveless with sweet gathers at the neck and a zipper in back. Label reads: Teddi. Medium size I'd say but do see measurements below. Looks and feels like nylon to me.
Excellent vintage condition. Near mint.

Measurements when lying flat. Doubled at bust, and waist
Armpit to armpit across bust: 37" at rest to about 52" stretched
Waist: 35" to 52"
Shoulder to bottom hem: 21.5"
