Jinx's in-game design contains a fairly petite height, standing at the short stature 5'3" while sporting an exaggerated slender form that includes a narrow abdomen and sinewy arms and legs.

She has bright blue hair that has a large swoop bang facing her left, with her hair tied into two tight braids that fall over her mid-back and cascade to her ankles.
Nearly touching the pavement.

Her attire consists of a smooth sharpish leather v neck bralette. With a mixmached design on both straps.
