Outfit

Sasuke is a fair-skinned ninja who has onyx eyes and black chin-length hair. His hair is spiky in the back with bangs that lengthen as the story progresses. As a young child, his bangs hung above his eyes. Later, they would hang on both sides of his face to roughly frame his cheeks and later again return to their original style. Sasuke is considered quite handsome as most girls near his age become very infatuated with him. At the beginning of Part I, Sasuke's clothing consisted of the traditional Uchiha clothing: a blue, short-sleeved shirt with a high collar and the Uchiha crest on the back and white arm warmers, which he stopped wearing after the Chūnin Exams, along with white shorts. In the last stage of the Chūnin Exams, he wore a black, one-pieced version of this outfit with many small arm-belts adorning his left arm and similar bands around both legs. As the story progressed, the Uchiha symbol became smaller and smaller until after he defeats his brother.

Initially, Sasuke wore a short blue-clothed forehead protector with the Konoha symbol on the metallic plate. After suffering a second defeat from Itachi, Sasuke stopped wearing it for some time. He put it back on during the latter half of his battle with Naruto at the Valley of the End, only to let it drop off at the end. Since then, Sasuke hasn't worn a forehead protector.

Sasuke's outfit later on in Part II.

In Part II, Sasuke has grown noticeably taller over the two and a half years and more muscular. He was first shown wearing a white long-sleeved shirt, similar in appearance to the lavender long-sleeved shirt worn by Kimimaro and which was open at the torso, with a smaller version of the Uchiha crest on his collar. He wore dark blue pants with a blue cloth hanging from halfway up his stomach to his knees. He also wore black arm-guards that covered his forearms and stretched up to reach his upper biceps. He also wore a purple rope belt around his waist, tied in a bow, in which he carries his sword.

After battling Deidara, he switched to a sleeveless dark grey shirt. His arm-guards were also removed, and he started wearing bandages on his wrists, under which he wore special armbands with seals where he stores various shuriken. He also wore a black cloak with this.

After he encountered and battled Itachi, he reverted to a grey high-collared short-sleeved shirt similar in appearance to the blue shirt he commonly wore in Part I but with a zipper. He also wears blue wrist warmers with his shuriken armbands hidden underneath. He briefly wore an Akatsuki cloak along with this. Another noticeable trait is that along with this new outfit, Sasuke began letting his hair hang over his forehead. The Uchiha crest on the back of his outfit has returned to its original size since his battle with Itachi. While adjusting to Itachi's eyes at the Mountains' Graveyard, he is seen wearing black Uchiha robes similar to those worn by Madara in his youth with a belt sash around his waist, though he would revert back to his previous clothing.

During his early childhood, Sasuke wore a simple long-sleeved black shirt with a raised collar and the Uchiha crest on the back, and black shorts (white in the anime). When Sasuke joined Itachi on his mission to capture the wild boar, Sasuke was wearing the ANBU uniform.
