Vintage Blue Hoodie Sweatshirt from the 70s/80s

Here is a great vintage hoodie from the 70s/80s. Most likely a blend of cotton and polyester. Lovely blue color with white piping accents. Two snap collar and single pocket on the front.  It's medium weight, super soft and comfy. There are several white stains on the back and sleeves (see pic four). I thought at first it was bleach, but I treated one and it got lighter. So maybe with some more effort, you can get them out. Regardless, on a shirt like this, wear like that looks awesome. To me, anyway. It's in otherwise amazing 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) 21"

Shoulder to end of sleeve (including cuff) 23"

Length 23"
