Vintage Long Sleeve Sweater by Christian Dior Monsieur

Here is a super cool vintage sweater from the 70s by Christian Dior Monsieur. I'm not sure of the fabric, but it is incredibly soft. Red fabric with trademark Dior embroidered on the front left breast in white. It's fairly light weight, sheer, soft and comfy. It's in amazing condition with years of life left! The tag says Large, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 22"
Sleeve 25"
Length 27"
