Vintage Ribbed Turtle Neck by Express
Here is a wonderful long sleeve turtle neck from the 1990s by Express. It's a blend of cotton, polyester, and spandex, and made in the USA. Tan color with vertical ribbing throughout. Medium light weight, soft, comfy, and in amazing condition with tons of life left! The tag says Medium, but here are the measurements taken laying flat (please refer to the last pic to see how I measure sweaters)
Chest (armpit to armpit) 16"
