Vintage Sleeveless Blue Sweater by Hot Connection

Here is a super cool vintage sweater from the 70s/80s by Hot Connection. 100% acrylic. Medium blue fabric with low slung front, and vertical pleated striping in the knit. It's fairly light weight, soft and comfy. It's in excellent condition with tons of life left. The tag says Medium, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 16" (this number could be way higher due to how the sweater is cut. If you have any questions about fit, let me know!
Armhole 12"
Length 20"
