Mossimo Swim Cover-Up — Effortless Poolside Style
Our Mossimo cover up delivers effortless poolside style when you need a breezy layer between the water and your next destination. We crafted this piece with a lightweight woven fabric that drapes beautifully without clinging, so you stay cool whether you're walking the boardwalk or grabbing lunch at the beach club.
We chose a plain-weave cotton for our Mossimo cover up because it strikes the perfect balance between structure and softness. The fabric holds its shape without stiffness, so you get a clean drape that moves with you rather than billowing in the wind. Each cover-up is cut on the bias to enhance the natural give of the weave, which means it stretches slightly at the shoulders and relaxes through the torso.
Sizing & Fit Guide
The Mossimo cover up runs true to size with a generous cut through the bust and hips. We recommend ordering your usual top size — the open front means you don’t need to worry about closure gaps, and the relaxed fit accommodates layering over bikini tops or one-piece suits without bunching.
Length Options
Our standard length hits at the hip on most body types, providing coverage for the lower torso while leaving your legs free. If you’re between sizes, we suggest sizing up for a longer, more tunic-like fit. The fabric won’t cling when damp, so an oversized look still maintains a flattering silhouette.
Care Instructions
Machine wash your cover-up in cold water with like colors after each beach day. We designed the cotton weave to withstand frequent laundering, but skip the bleach — it can weaken the fibers over time and fade printed versions.
Tumble dry on low heat or hang to air-dry in the shade. High heat can shrink cotton, so if you prefer the original relaxed fit, pull the cover-up from the dryer while it’s still slightly damp and lay it flat to finish drying. Press with a warm iron if needed, though the natural texture of the weave looks best with a lived-in, slightly rumpled finish.

Common Questions About Our Swim Cover-Up
The cotton weave may shrink slightly in hot water or high heat, so we recommend washing in cold and tumble-drying on low. If you prefer to maintain the original relaxed fit, remove it from the dryer while still damp and lay flat to finish drying. Following these care steps will keep the cover-up true to size over time.
The plain-weave cotton offers moderate opacity when dry and will show some transparency when fully saturated. It’s designed to be worn over swimwear, so any see-through effect is minimal and typical for this style of cover-up. The fabric dries quickly, usually within 15 to 20 minutes in direct sunlight.
Yes, the open-front design and neutral styling make it versatile enough to wear as a lightweight cardigan over tanks, tees, or casual dresses. Many customers layer it with shorts or jeans for everyday summer outfits. The unlined construction keeps it breathable for all-day wear.
The standard length measures 28 inches from the center back neck to the hem on a size medium, which typically hits at the hip on most body types. If you’re looking for more coverage, sizing up will add a few inches to the overall length and create a more tunic-like fit.
This design does not include pockets. We kept the construction minimal to maintain a lightweight, packable profile that’s easy to toss in a beach bag. The open front and relaxed cut prioritize airflow and quick drying over added features.
Solid colors offer maximum versatility and pair with any swimwear pattern, while our stripe and coral reef prints add visual interest if you prefer a coordinated beach look. All colorways are made from the same cotton weave and have identical fit and care requirements, so the choice comes down to personal style preference.
The relaxed fit and open-front design accommodate a wide range of body types. We offer extended sizing up to XXL, and the generous cut through the bust and hips ensures comfortable layering over any swimsuit style. Check our detailed size chart for bust and length measurements to find your best fit.
