This is a true vintage men's shirt by Prada.
Sorry about the photos - really hard to photograph black! The marks in some photos are on the lens, not the garment!
In a heavy stretch jersey, slightly ribbed, good quality true black fabric.  Feels like cotton or cotton mix.
Epaulettes to shoulders, patch pockets, unlined, button up, short sleeved. Slightly military look
Close fitting with stretch.

Great designer piece with nice attention to detail.

Has been worn, but fabric holds shape well and there are no obvious marks, tears, rips etc.
