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.
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 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, such as portraying herself as a futuristic and highly destructive robot in an assignment asking a student "How do you see yourself in the future?"
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 also enjoys cheese.
