We follow standard sizing guidelines and make our products true to size.
Our swimsuits are constructed with a firm fit to flatter your shape. If you are between sizes, we recommend choosing the larger of the two sizes. For example, if you wear a size 10 in the top but a size 12 on the bottom (or vice versa) we recommend you purchase a size 12.

Our swimwear is designed for a firm, flattering fit. If you find yourself between sizes, we recommend selecting the larger size for optimal comfort.
How to measure
- Bust: Using a flexible tape measure, measure across the fullest part of your chest, ensuring the tape measure is straight across your back.
- Underbust: Measure directly under your bust, where the band of a bra would sit.
- Waist: Measure around your natural waistline — this is the narrowest part of your torso, usually right above your belly button.
- Hips: Stand with your heels together and measure around the fullest part of your hips and bottom.
