ABOUT US

Margaux Sur Mer is a luxury swimwear brand designed for women who want swimwear that works—without sacrificing style.

Founded by Elizabeth Petersen, the brand was created in response to a common frustration: most swimwear is either beautiful but impractical, or functional but uninspired. Margaux Sur Mer sits at the intersection of both. Each piece is designed to offer thoughtful coverage, support, and ease of movement, while maintaining a refined, timeless aesthetic.

The collections draw inspiration from the clean lines and restraint of 1960s and 70s style, coastal living, and a lifestyle shaped by travel. Designs are intentional rather than trend-driven, created to be worn repeatedly, styled easily, and relied on season after season.

Margaux Sur Mer swimwear is crafted in Europe using high-quality fabrics selected for durability, comfort, and performance in and out of the water. Every detail—from fit to fabrication—is considered with real wear in mind.

This is swimwear for women who are active, confident, and discerning. Women who value quality over novelty, simplicity over excess, and pieces that integrate seamlessly into how they actually live.
