Plus-size swim dress for women by SwimZip

Plus-sized swimwear problems

Plus-size swimwear spans sizes XL–3XL (14–24). With larger sizes, your swimwear's design, quality, fit, and features impact beach-day comfort. Plus-size women face these common swimsuit problems:

Shoulder straps dig into the skin during beach activities
Small cups squeeze and distort the bust shape
Unsupported busts sag in the water
Bottoms ride up or slide down during swimming
Tops pull away from the body when moving
Rough fabric chafes between the thighs
Thin material becomes transparent in water
Hard underwires poke and pinch the skin
Stretched-out elastic after several uses

SwimZip's plus-size swimsuit collection uses premium fabrics, strong support structures, and figure-flattering cuts that stay in place.

What is a swim dress?

A swim dress is an elegant, modest alternative to conventional swimsuits such as bikinis. In recent years, swim dresses have gained popularity as more women search for a stylish yet conservative option for water activities.

The swim dress appeals to women who want a comfortable, confidence-boosting option for swimming and beach outings. It merges practical swim features with the stylish coverage of a dress.

Through this mix of function and style, the swim dress is a comfortable, modest option in women's swimwear.

Our flattering plus-size swim dresses

Plus-size swimming dresses give you style and coverage in one piece. These suits mix dress-like cuts with practical swim features: soft fabrics, adjustable fits, and quick-dry materials.

Half-zip or quarter-zip

Some of our plus-size swim dresses have a half-zip design that adapts to your coverage needs. A half zipper extends to the bust line, so you can zip up for full coverage or unzip for a casual scoop neck style. The metal zipper chain adds a subtle gleam to your suit.

Our beach dresses include quarter zip accents for a refined touch of hardware. The zipper runs 4–6 inches on the dress front for neckline control without impacting the dress's comfort or function.

Adjustable ruching

The ruched texture comes from pin-tucked fabric that accentuates your curves. This creates a smooth silhouette that flatters your natural shape. All our plus-size swim dresses have adjustable side ruching ties for a custom fit.

Adjustable ties

The smart ties on our plus-size swim dresses fit curvy bodies like a glove. Women with full busts can set the fit exactly where they need support and coverage. The ties adjust as sizes change and create a natural cinched silhouette.

Plus-size range

Our swim dresses go from XL to 3X to celebrate every curve. Find your style and fit in our size-inclusive collection.

UV protection

Our long-sleeve swim dresses stop 98% UVA and UVB rays with UPF 50+ fabric. Extra protection and all-day comfort mean you can enjoy the sun longer.

Our premium swimwear fabric

SwimZip fabrics shield you through swimming, surfing, and beach play. Our quick-dry materials pull water from your skin for total comfort in waves or on sand. The fabric resists chlorine, salt water, and sun damage.

For powerful sun defense, our UPF 50+ technology stops 98% of harmful UVA and UVB rays to prevent sunburn, aging, and skin damage in the outdoors.

Four-way stretch fabric follows each twist, reach, and swim stroke. The material rebounds without losing shape—no pulls or adjustments needed. You move freely whether you’re playing volleyball or swimming laps.

Our fabric traps a warm water layer that keeps you comfortable in cool water. Strong seams and snag-resistant fibers prevent tears, so your suit lasts season after season.

How can I style my plus-size swim dress?

Swim dresses don’t have any support features and are open-ended, so they are great for pairing with other tops and bottoms. Try pairing your plus-size swim dress in any of these fun, fashionable ways:
