Authentic vintage Women’s Halter top. Stretchy polyester type material with the iconic lime green, orange, brown, yellow, etc combination. Tag says S. Here are the measurements. Bust 16” pit to pit. Waist is 11” - The green waist band is ribbed and stretchy. You could probably get another 1” - 2” or more? for the waist. I’m thinking this is more is an XS in modern sizes. Fantastic find and would groovy with a denim skirt, shorts or lightweight cottage-core type skirt. Thanks for looking.
