While still a pirate, Zeff has short blonde-hair, which is somewhat unkempt, a mustache that he tied with light blue ribbons on each end, and a slight stubble.
22 years before the story, he wore a simple red-and-white vertical stripped shirt with gold buttons on the collar. By the time he raided the Orbit, he changed to a purple and red, horizontally stripped overall and braided his mustache. In either case, he wore dark pants with a light green pirate's sash and a captain's coat draped over his shoulders like a cape.
As the head chef of Baratie, Zeff is an elderly-looking man who still retains his blonde-coloured hair, which he keeps underneath his extra-long chef's hat. His mustache has grown considerably long, and he grew a beard. He wore his chefs uniform, with a blue ascot, and white apron. Also, since he lost his left leg, he has a peg leg. and he seems to have no trouble walking with it.
After two years, he wears a striped dark colored and light colored shirt, dark colored pants, and a white chefs uniform draped over his shoulders, with his ascot. He still has the same braided moustache style, and peg leg.
Zeff was a tough former pirate. He is hard on those around him and is always serious about everything. Zeff normally doesn't show emotions other than a hot temper and has a firm hold of authority at the Baratie.
As a chef at sea, Zeff respects food to a very high degree. When he ordered his crew to plunder the Orbit, he kicked one of his crew for stealing food, the one thing he refuses to take. Also, when Sanji was still in-training at the Baratie, when his food was unsatisfactory for customers, Zeff forced Sanji to eat it himself, rather than throw it out. He also gave Krieg food for his starving crew, understanding the pain of hunger at sea, despite knowing that feeding the crew would bring a battle.
