Orihime is a teenager of average height. She has brown eyes and long, waist-length burnt orange hair. Her most noticeable physical trait is her slender yet curvaceous figure for a teenager, especially in terms of her large breasts. She wears her hair in bangs tucked behind her ears with hairpins, which she only removes to sleep, as they are worn in the memory of her brother.
Orihime is independent, friendly, humorous, sensitive, caring and kind. She comes off as naive and rather clueless, which is at odds with her exceptionally high marks in school. She studies hard because when her grades drop, she receives less financial support from her relatives. She is a member of the Handicrafts Club and likes to invent very ridiculous sports to play with Tatsuki (such as "base-cer," a combination of baseball and soccer). She tends to zone out with her mouth open and loses track of what she was thinking or dreaming about. She has an over-active imagination and gets carried away thinking of implausible scenarios.
Orihime likes Asian flower print clothing and comedies. While she does eat some normal food, Orihime cooks and eats unusual meals, which other people often find unappetizing. Her favorite food is red bean paste and she likes putting butter on sweet potatoes. She enjoys cheese and butter most of the time.
Orihime has demonstrated that she is perceptive when it comes to people's mental and emotional state, especially in regards to Ichigo, as she is able to tell what kind of driving force is pushing someone. She additionally has a crush on Ichigo.
