Athanasia is depicted with long, wavy blonde hair usually tied back into a high ponytail, with soft bangs falling into her jewel-blue eyes, the trademark of the imperial family. Her appearance is often compared to that of her mother, Diana, and she is described by many characters to be exceedingly beautiful. Throughout the series, Athanasia wears a variety of different gowns made of fine materials, paired with ornate accessories befitting of a crown princess.
