*"Cat Burglar" Nami is the navigator of the Straw Hat Pirates and one of the Senior Officers of the Straw Hat Grand Fleet. She is the third member of the crew and the second to join, doing so during the Orange Town Arc. She is the adoptive sister of Nojiko after the two were orphaned and taken in by Bell-mère.

Nami is a slim young woman of average height with ginger (orange) hair and brown eyes. Many characters seem to consider her to be an attractive woman. She has a black tattoo (blue in the anime) on her left shoulder, which represents mikan, and pinwheels (a homage to Bell-mère, Nojiko, and Genzo, respectively), where she used to have a tattoo for being a member of Arlong's crew.

Her overall physique matures slowly throughout the series and then suddenly during the timeskip (though this is most likely a simple change in style of artwork). Her fashion frequently changes as does her hair style. Many of her shirts feature four-letter words, such as "Gold" or "EVIL", similar to a shirt that Bell-mère once wore that had "MACE" on it. On her left wrist, she wears the Log Pose, which she needs in order to be the navigator of the ship, and a gold bracelet, given to her by her sister, Nojiko. After the Arlong Park Arc, Nami frequently changes into a variety of clothes in the series for each arc, and usually pairs her tops with skirts that have two rings on the sides. Her trademark shoes are orange high-heeled gladiator sandals. Nami wears some form of high heels in every arc, and while they do make her taller, they do not seem to affect the way she walks or her speed. Though she tends to style her hair neatly, occasionally, a hair on top of her head may form into a messy cowlick.

She wears a strap around her thigh with three slots in it which she keeps each pole of her bo staff and later the Clima-Tact in.

Nami's appearance underwent a few significant changes. Her hair has grown longer, reaching down her lower back with a single long hair stand hanging on the left side while still maintaining her bangs. Her breasts have also grown much larger, and she has developed more of an hourglass figure, similar to Nico Robin's. Nami has also grown slightly taller. After the timeskip, her default outfit consists of a revealing green-and-white bikini top, tight low-rider blue jeans, orange high-heeled sandals, and a pair of pearl-like earrings. Since arriving to the New World, Nami sports a new belt that is black with a " Beli " symbol on it, where she keeps the pieces of her Sorcery Clima-Tact on the right side.
