Here is a cool vintage button down shirt by Gentry Prep. Feels like a poly and cotton blend. Classic plaid in blue, brown, and white. Six button front, button down collar, a button at the back of the collar, and a pocket on the left breast. Nothing super fancy, just timeless good looks. Thin, fairly sheer, soft, and comfy. It's in amazing condition with years of life left! The tag says Size 18, 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) 9"

Length 27"
