Also known as: レイヤードビキニ, 层叠比基尼
A Bikini that has two or more discernible layers. A simple example involves wearing a highleg bikini as the lower layer, then a lowleg bikini as the upper layer, resulting in the sides of both being visible on the character's thighs, not to be confused with a Ruffle Bikini.
If one of the layers is a One-Piece Swimsuit, then also add the tag Layered Swimsuit.
