James McGill (Bob Odenkirk) wears this black double breasted suit in multiple episodes of Better Call Saul.
It is Custom Made.
“Those suits are my design. What I did was I had the suits made in Italy, and then I tweaked the suits. I placed the buttons on the jacket higher than they should be. They were so high that Vince [Gilligan] labeled them “nipple buttons.” We changed the slope of the shoulder. They’re a bit big for him, but not too big where he looks cartoonish. I moved pockets to the wrong side, like the ticket pocket, just tweaked it and tweaked it until it was just, just off. And it was very interesting because the Italian tailors were like, “This cannot possibly be correct! This is wrong!” It took a little bit of persuading and it went against their tailoring DNA, but they did as I asked.” – Jennifer Bryan (Costume Designer)
