Mulan is a young tomboy of Chinese origin. She is a natural beauty, with dark brown eyes and straight, black hair that used to be long and waist-length. Later in the film when she leaves to join the army in disguise, she cuts her hair with her father's sword into shoulder-length and ties it up in a bun. This helps her blend into the army so that the other soldiers don't know that she's really a woman. In the second film, her hair was grown. Not to its original waist-length, but it's noticeably longer a few inches longer towards her back. In promotional works, her hair is always shown as its original length, down to the waist.
During the two films, Mulan wore a range of outfits, from beautiful Hanfus (Chinese dresses) to her soldier's getup, though her most notable outfits come from the original film; in which her promotional dress comes from, which is a simple Hanfu, which consisted of either a creamy green-yellow dress, with blue over shirt, which has green sleeves, and a red band around her waist. She also sports a kung fu styled soldier's outfit, as well as her pink matchmaker's Hanfu and her father's armor.
Except when she goes to the matchmaker, Mulan does not wear any makeup or anything to beautify her appearance. Mulan is naturally beautiful nonetheless.
When she sleeps, she wears a light blue tank top, short blue shorts, and is barefoot. She wears a dress consisting of a green long-sleeved shirt with olive brims and both yellow skirt and inside shirt with a low cut neckline, blue wrap, red waistband, and black ballet flats, but also has been seen barefoot as well. To impress the matchmaker, she had her face painted in white, red lips, black hair tied in a loose bun with a red hair ribbon, narrow crimson and pale pink Chinese skirt, pink jacket with long, flowing sleeves, aqua and plum collar, blue wrap with a red ribbon to fasten it, light purple scarf, same color shoes, jade bead necklace, gold dangling earrings, and a special lotus flower hair pick. When she was disguised as "Ping," she has black hair tied in a bun with a teal ribbon to look like a man (when she cuts her long, beautiful hair with her father's sword into a shoulder-length), and dark green soldier armor.

In the Shan Yu battle, she wore a teal dress consisting of a poet-sleeved blouse, long olive vest with a crimson collar, crimson belt, light pink sash, and same color shoes.
