Claire is a young woman with a tall, slender figure, fair skin, a voluptuous chest, and shapely legs. She has long, silky black hair that reaches down to her knees and striking red eyes, which are often compared to her brother’s. Many describe her appearance as nothing short of "stunning."[7] Her right-side bang is longer than her left, mirroring her brother’s hairstyle. She wears the Midgar Academy for Dark Knights uniform, which consists of a gold-detailed blazer with white cuffs, a white dress shirt, a navy-blue tie, and a plaid-patterned skirt. She also wears a navy-blue waist belt with gold accents, black tights, and knee-high heeled boots with crosscut laces.
After becoming the vessel of Aurora, she placed a magical seal on the back of Claire's hand. She would start to conceal the seal on her arm with a white bandage wrapping around her arm.[11] After having the severed right arm of Diablos forcibly bound to her body, a second magic circle appeared on her hand.[14]
In the past, Claire's long hair reached just below her shoulders, but over time, it grew to her waist, cutting straight across her back. Eventually, her hair extended past her waist.
