When a female's full covering bikini tan lines leave her buttocks ghostly white while her legs, stomach, and back are beautifully tan leaving her to look like she is wearing a diaper while in the nude.
A Diaper Tan is when a girl is fully nude and her body while beautifully tan, is white around her private parts and buttocks leaving her looking like she is wearing a diaper.
