Kuzan is an incredibly tall, slim and muscular man, roughly of the same size as the other two admirals Sakazuki and Borsalino,[7] the latter clearly taller than Brook but it seems that he also is shorter than Doflamingo who is 305 cm (10'0") tall. He has black, curly hair cut to chin length that fans out at the tips, tanned skin and an altogether lean, long built.
His standard outfit while in the Marines consists of a white buttoned-up vest with standing collar over a long-sleeved navy blue shirt and matching white trousers and shoes, rarely accompanied by a matching suit jacket
[8]. He also wears a yellow tie divided geometrically by black lines and a sleep mask on his forehead. During his preparations for the war against
Whitebeard, Kuzan has a white Marine admiral's coat (golden epaulettes and for him being the ice user, blue cuffs) draped over him like a cape, as did the other admirals. He also is seen wearing a green and purple sleep mask at all times two years ago from the present timeline.
[9] In contrast to Borsalino and Sakazuki, Kuzan is far younger than his colleagues, being less than fifty years old; altogether, his looks, combined with his manner, make him appear even younger than he actually is.
As a child Kuzan had a grimace on his face. He wore a dirty light blue shirt and a purple pair of shorts with white stripes. He carried an umbrella tied on his back, a bottle of alcohol and a backpack. Also, his hair was curlier compared to his current hairstyle.
In his youth, Kuzan wore a white marine cap and a shirt.
