Rydia is introduced as a seven-year old girl wearing a yellow skirt and a white cloak. In her sprites her clothes are blue, while they are black in Yoshitaka Amano's artwork of her, and dark green in her 3D remake model. Following her return as a young woman, Rydia wears a green outfit with knee-high golden heeled boots and draperies adorned in stars. During Final Fantasy IV: The After Years, Rydia's attire is a single-piece green outfit that rises from her thighs to her collar, baring her hips and upper torso.
The overseas releases of The After Years censored her artwork, which included a green skirt, and covered the exposed areas of her body, as was done with Porom and Ursula, but Rydia's artwork received the most censorship. The opening movie for Final Fantasy IV: The Complete Collection uses this design. Rydia's hair is green, shoulder-length in Final Fantasy IV and extending past her waist in The After Years. It is often complemented by a hair ornament which has varied in design.
