Vintage Red and Black Sweater by Forte
Here is an awesome vintage sweater by Forte. It's 100% acrylic. Great geometric design in red and black. It looks a little purple in the pics, but it's red. Fairly heavy weight, but soft and comfy, and super warm. It's in amazing condition, and has years of life left. The tag says Small, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)
Chest (armpit to armpit) 20"
Shoulder to end of sleeve (including cuff) 25"
