Sam wears this while making bullets and arguing with Castiel in 10.23 Brother’s Keeper. He wears it in There’s Something about Mary, in Wayward Sisters, and The Big Empty.

This is one of those infuriating shirts with half a dozen models of it out there. Sam's version is a MOCK western cut with snaps and a decorative shoulder seam over an UNCUT piece of fabric, it's truly a marvel of reverse engineering. Soft, lovely drape, fade overwash. There are actual western cut versions that are NICER than Sam's version as well I'll offer those as alts if I see them and *cough* buy them by accident.
