To find your perfect size, please refer to our size guide. Our swimsuits are designed to be supportive and comfortable. So if your measurements put you between two different sizes, we would generally suggest sizing down—but you should go up or down depending on your fit preferences.

If you like your swimwear to fit snugly and to feel more compressive, pick the smaller size. If you like a more relaxed and comfortable fit with room for body shape fluctuations, go for the larger size. 

In most cases, we’d advise to opt for the smaller size—swimwear looks best when it fits snugly, in our opinion!
