Vintage Long Sleeve Sweater by Knitting Arts Studio

Here is a super cool vintage sweater from the 80s by Knitting Arts Studio. Feels like a blend with maybe some wool. Gorgeous maroon background with red striping across the chest. It's medium weight and soft, warm, and comfy. It's in excellent condition with tons of life left. Here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 15"
Sleeve 20"
Length 21
