Good god, those ties and pockets squares are something straight out of an 80's drug lord film.

The costumers did a great job on this show. Hannibal's clothing is out of the ordinary, but that makes sense for his character. He seems to love obscure and refined things. It would be kind of a mismatch for someone who cooks like Jose Andres to wear the most conservative, traditional, and nondescript wardrobe possible. I wouldn't try to emulate his style because I don't think it would work for me, but it's great eye candy within the context of the show.
