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.
For the woman who values pieces that will take her from day to night. This is resort dressing, resolved in one considered edit.
The set includes three elevated essentials — the Classic Square Neck One Piece, the Modal Lace Trim V-Neck Nightie, and the Beach Sarong.
The one piece is beautifully structured and fully lined, offering a sculpting fit with a clean square neckline. Layered with the Modal Lace Trim V-Neck Nightie, crafted in butter-soft modal with delicate stretch lace detailing and a flattering V-neckline for understated femininity. Finished with a lightweight midi sarong for effortless coverage and an easy drape.
Discover pieces made for every moment of the day.
