I just finished binging Sneaky Pete on Amazon Prime (I recommend both seasons, BTW). In Season 1, episode 10, Giovanni Ribisi wears a suit that I'd like to identify or find a close facsimile. The best picture I can find is below.

It's a grey material with a sheen, but not an overbearing shininess. It looks like there is pick stitching on the notch lapels. No idea if it is custom or OTR, but I believe that costume designers do a lot of custom work.

Any ideas?
