Vintage dark green button down shirt

Vintage dark green button down top. Collared. Long sleeves. With thin shoulder pads. No tags, not even for size. My estimate is a medium but I'll measure if anyone is interested. Material is very smooth, velvety-like but I'm not sure exactly what it is. Kept in storage for a very long time thus the folds and wrinkles. NWOT. #buttondowntop #buttondownshirt #vintageshirt #nwot #worktop #workattire
