CHEEKY CUT / FULL COVERAGE

Our Cheeky/Full-coverage swim bottoms prioritize comfort and modesty, offering the most fabric across the back and often sitting lower on the hips or at the natural waist. They provide a secure, stay-in-place fit that’s great for active beach days or simply feeling more covered. The shape smooths and supports the hips and rear while still giving a flattering, body-conscious silhouette. This classic cut is a timeless choice for those who want confident coverage without sacrificing style.

SEMI CHEEKY / MODERATE COVERAGE

Our Semi-Cheeky swim bottom strikes a balance between modest and daring, offering moderate back coverage that reveals just enough.

SEMI BRAZILIAN

Our Semi-Brazilian swim bottom offers a happy medium between Brazilian and Semi-Cheeky.

BRAZILIAN BOTTOM / MINIMAL

Our Brazilian swim bottom is known for its minimal rear coverage.

MEN’S TRUNKS

For the perfect merman. Designed for comfort, these shorts feature a mesh liner, an elastic waistband with 4-way stretch and a drawstring for secure closure.

MEN’S BUTTON-DOWN SHIRT

    Confidence Boosted 100%

    Honestly one of my favorite things about the suit is how flattering and confidence boosting it feels while still being incredibly comfortable. The fabric is buttery soft, the quality feels amazing, and every little detail feels so intentional from the fit to the design to even the packaging and swim bag ✨

    What really stood out to me is that it genuinely does not feel like every other swimsuit brand. The styling is so unique and elevated, and it fit the whole western desert vibe of the shoot perfectly. I’ve already gotten so many compliments and questions about where the suit is from, which honestly says a lot. Whether it’s a pool day, vacation, or styled shoot moment, Salty Mermaids doesn’t miss! 🧜🏼‍♀️

    Amazing

    True to fit soft, great craftsmanship very sexy on. I’ve been told by many that have seen the photo of me in it. I look amazing for a 60-year-old woman in that suit. I’m rocking it someone said.

    Beauty in colors

    This bathing suit is a rainbow of colors. The fit is superb and the material is soft and stretchy, but not too stretchy that it doesn’t hold your shape. Was so glad when I found this on salty’s website.

    Poolside & Passport Ready

    This is one of those swimsuits that instantly makes you feel put together. I wore it at the resort pool during the day and styled it with flowy pants for dinner by the marina at night. Comfortable, beautiful, and definitely one of my favorite travel pieces

    Perfect for Tulum

    I packed this for a tropical getaway and reached for it constantly. The cut is stunning, the fabric feels amazing, and it photographs beautifully in natural light. It has that effortless vacation energy I love.
