TWO-PIECE SUITS 
Fits true to size, but refer to product images for a clear idea on how they look on. Some women prefer more bust coverage so will opt to size up. Please note that the IDA bikini has larger triangles/thicker material, whereas SORA, JO, and YUME use thinner material, and have smaller triangles.
