Nami

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.[21][22] She has a black tattoo (blue in the anime)[23] 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.[2]

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.[24] 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.

Along with Nico Robin, Usopp, Sanji, Tony Tony Chopper, and Franky, Nami is one of the smartest of the Straw Hats. And according to an SBS from volume 8 (1999), Oda said that "of all the characters introduced so far in One Piece" Nami was the third smartest character in the East Blue (the first is Benn Beckman of the Red Hair Pirates, the 2nd being Captain Kuro).[19] Though given how few characters were introduced and properly developed at that time, that quote should be taken with a grain of salt.

At the beginning of the series, Nami despised all pirates. She viewed them as universally evil after losing someone close to her to pirates, only changing her mind after she met Luffy (although Nami still reminds Luffy that not all pirates are like him). Before her view on pirates changed, she was perfectly fine with giving a captive Luffy up to Buggy but refused to kill him when asked by Buggy to do so, as she could not bring herself to stoop to their level. Nami has been deeply affected by her adoptive mother's death and Arlong's enslavement and imprisonment of her. She remembers vividly of the abuse she suffered such as one of Arlong's crewmates refusing to feed her as well as the pain and exhaustion on the streets from stealing money in an attempt to buy back the village from Arlong.[20] Upon failing to do so, Nami was utterly distraught and when Genzo and rest of the villages went to die for her, Nami took the knife she was holding and madly stabbed her shoulder before Luffy stopped her. Her experiences left Nami with many painful memories, that she has since then successfully buried but Nami still retained a fear and distrust of the Fish-Men race as a whole until she learned the painful history of human cruelty towards Fish-Men. By the time the crew reached Fish-Man Island, she was willing to give Fish-Men a chance and even befriends some of them while claiming she solely held a grudge against Arlong.[21]

Nami is also disbelieving in myths and legends, as she dismissed Devil Fruits as myths, disbelieved the existence of Skypiea, and was dubious over claims of a connection between Sanji and the "mythical evil army", Germa 66. Ironically, all these legends were proven true to her when she saw Buggy's Bara Bara no Mi in action, when Robin insisted that the Log Pose pointing at Skypiea was proof of its existence, and when Pekoms confirmed Germa and Sanji's history together. Nami was shocked to see and hear that she was wrong but slowly accepted the unbelievable things in front of her.

Nami can be seen ordering the crew to lift the mast or draw the sails. If she deems an island dangerous, she will often try to convince Luffy (usually along with Usopp and Chopper) to not go there but will nonetheless follow Luffy's orders when he demands so. She seems like a coward, but she has been referred to by multiple people being a "bold woman." Usually, she is called that when she stands up for her crew and what she believes to be right. She is aware of the dangers they face every day and has a much better understanding of the world and its more dangerous individuals (e.g., the Seven Warlords of the Sea) than most of her crew does, though lacks Robin's knowledge on some of its other powerful figures (e.g., the Marine Admirals) and organizations (e.g., the Four Emperors). She can be devilish and cunning at times,[22] and if she feels like it will even give her fights to Luffy, Zoro or Sanji. She is the only one among the crew to be visibly concerned and upset whenever their bounties go up, something the others usually react to with indifference or even joy. She’s unapologetic too and stays angry whenever arguing with someone.

From the Return to Sabaody Arc through the Fish-Man Island Arc, Nami's appearance has undergone a few significant changes, including her hair having grown rather long, reaching down her lower back with a single long hair stand hanging on the left side with bangs still hanging over her forehead. Her breasts have also grown much larger/rounder similar to Nico Robin's, but apart from this, her appearance has not changed much, save for the fact that both her body curves and hourglass figure have become more pronounced. Oddly, Nami's face is now drawn to look younger with her eyes bigger (with the irises now showing), droopier and placed lower on her face; though this may be from the art style evolving. She also has grown slightly taller. After the timeskip, her outfit consists of a revealing green and white bikini halter top, tight low-rider jeans (that expose a bit of her hips and rear), orange high-heeled sandals and a pair of pearl-like earrings that she constantly wears. Ever since arriving to the New World, Nami sports a new belt that is black with a " Beli " symbol on it where she can also keep the pieces of her Sorcery Clima-Tact on the right side and puts the belt around her waist when she is fighting seriously against an opponent.
