Nami Timeskip

"Cat Burglar" Nami is a pirate and the navigator of the Straw Hat Pirates. She was officially the third member of the crew after Arlong's defeat, and the second to join. She briefly betrayed the crew during the Baratie Arc, but rejoined at the end of the Arlong Park Arc after her past and true intentions were revealed. She has a bounty of Beli16,000,000.
After timeskip
From the Return to Sabaody Arc through the Fishman Island Arc, Nami's hair has grown rather long, reaching down to her lower back. Her breasts have also grown larger and rounder, like 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, her 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 appears to have grown taller, as she appears to be just slightly shorter than Robin now (although they are both wearing high heels). Her outfit after the timeskip consists of a revealing green and white bikini halter top, tight low-rider jeans (that expose some of her hips), orange high-heeled sandals, and a pair of pearl-like earrings.
At the start of the Punk Hazard Arc, when they arrived in the New World, after bathing, Nami changed to a red and yellow Criminal brand bikini top with the same pair of jeans. She also tied her hair back. When she reached the cold side of Punk Hazard, Sanji gave her his jacket to stay warm. She was later given a long black double-breasted coat by Kin'emon using his unnamed Devil Fruit power.
