something i notice in anime

So i recently watched Nekopara, and I really enjoyed it. Coconut was my favorite character, but while I was watching, the realization hit me that often in anime, tan girls like Coconut are given more revealing clothing than the other more pale characters. Does anyone know why this is/have noticed this aswell? I really love Coconut and I would h8 it if the reason tan girls are often shown like this is for some creepy or fetishy reason.
