The Mermaid Mafia Wide-Leg Sweatpants in Phantom Black are where comfort meets quiet power—designed for those who move with a darker kind of allure. Crafted with a 100% cotton outer and a soft 60/40 cotton-poly interior, they offer a plush yet durable feel with a relaxed, loose silhouette that drapes effortlessly. A striking swimming siren graphic glides along the leg, adding an artful, mysterious edge, while a hidden zipper pocket keeps essentials secure without disrupting the clean lines. Equal parts elevated and easy, this piece is a statement in subtle rebellion—an essential from the shadowed depths of the Sea of Sirens collection.

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

    Love these

    I’m honestly living in these. They go with every hoodie, tank, and tee I own. The shell detail is such a cute touch and makes them feel unique. They hold their shape, wash beautifully, and stay comfortable all day long. 10/10 recommend

    wide leg luxury

    The quality of these sweatpants is unreal. They feel thick, plush, and incredibly soft on the inside while still breathable. The wide-leg cut makes them feel elevated and stylish instead of sloppy. I never want to take them off

    I’ve searched forever for the perfect wide-leg sweatpants and these are finally it. The waistband is super comfy, the fabric feels buttery soft, and the length is perfect even with sneakers. I get compliments every single time I wear them

    EFFORTLESS

    These pants are everything. The fit is relaxed and flattering, and the wide leg style looks effortlessly cool without trying too hard. They’re insanely soft, cozy, and feel high quality not thin or cheap like most sweatpants. I wear them literally everywhere!

    Love how they fit

    I bought these for lounging and now I’m wearing them everywhere. They’re insanely soft, perfectly oversized, and somehow make me look cute even when I’m doing absolutely nothing. The wide leg gives that effortless, cool vibe without trying too hard.
