Plus size long-sleeve swimsuits

Swimwear challenges for plus-size women

Plus-size swimwear includes sizes XL–3XL (14–24). Women who wear these sizes face some serious swimwear challenges, including:

Shoulder straps that cause pain from digging in.
Cup sizes too small, leading to bust overflow.
Cups without proper support, causing sagging.
Swimsuit bottoms that shift and ride up in water.
Swimsuit tops that slide down during activities.
Poor materials and cuts that cause thigh irritation.
Thin fabric that becomes transparent when wet.
Uncomfortable underwires that press into the skin.
Stretched-out elastic after minimal washing.

Plus-sizes swimwear needs specific features for comfort, support, and style. SwimZip's plus-size collection solves these problems with high-quality fabrics, supportive designs, and flattering cuts.

Our stylish women’s plus-size swimsuits with long sleeves

Swim dresses

Our swim dresses take you from swimming to seaside lunch without missing a beat. A half-length zipper lets you quickly change, and side ties adjust the length from dress to shirt based on your activity. Long sleeves provide full coverage in sizes XL to 3XL, with plenty of room to move and stretch.

These smart design features make this dress a beach day must-have:

A protective neck collar sits high to shield your neck and shoulders from UV rays

Here is why plus-size women love our rash guards:

A high neck collar protects your sensitive neck and shoulders from UV rays.
A smooth zipper garage prevents chin irritation during movement.
An inner zipper guard keeps metal from touching your skin.
A tagless design fits comfortably against your curves.
Secure thumb holes keep sleeves in place while you swim, play volleyball, or enjoy pool time.

Why do women choose long-sleeved swimsuits?

Women choose long-sleeved swimsuits to get ultimate sun protection, comfort, and style all at once. Our UPF 50+ long-sleeve swimwear blocks 98% of harmful UV rays and provides coverage that makes you feel confident at the beach or pool.

Sun protection: A long-sleeved swimsuit shields your arms, shoulders, and chest from UV exposure. This coverage reduces your risk of sunburn and sun damage, especially during extended water activities. Unlike sunscreen, which requires frequent reapplication, UPF fabric maintains consistent protection all day.
Athletic performance: Long-sleeve styles give you the freedom to move without worrying about straps sliding or tops riding up. The sleeves stay in place during active water sports, from surfing to paddleboarding. Many styles include thumb holes to prevent sleeves from rolling up during intense activities.
Body confidence: Long-sleeved swimwear provides coverage while celebrating your shape. The sleeves smooth your arms and protect sensitive skin areas. Extra coverage lets you focus on enjoying water activities rather than feeling self-conscious about sun exposure or certain body areas.
Temperature control: Despite covering more skin, long-sleeved swimsuits help regulate your body temperature. The moisture-wicking fabric keeps you cool in hot weather and adds warmth during early morning swims or cooler beach days.
Practical benefits: These suits reduce the time and money spent on applying and reapplying sunscreen to your upper body. The durable fabric resists chlorine and saltwater damage, maintaining its protective properties through multiple swimming seasons.

How do I choose the right plus-size long-sleeve UPF swimwear?

Our plus-size long-sleeve UPF swimwear combines sun protection with a comfortable fit that moves with your body. Follow these tips to find the perfect suit for your needs:

Look for UPF 50+ fabric that blocks harmful rays while staying breathable.
Know your body shape. Pear, apple, and hourglass figures require specific support in different areas.
Choose your bust support. Whether you have small or big busts, you need proper cup structure and strap strength.
Choose suits with full-length zippers to avoid overhead struggles when changing.
Select a neckline that sits high enough to protect your shoulders and chest.
Check that sleeve cuffs include thumb holes to prevent riding up during activities.
Pick styles with side panels that stretch without becoming see-through.
Make sure the torso length gives you full coverage when reaching or bending.
Test that the arm fit allows comfortable movement without binding.
Check suits with tagless designs to prevent skin irritation.
Look for flat-lock seams that won't dig into your curves.
Pick a moisture-wicking fabric that dries quickly between swims.
Choose suits with chlorine-resistant materials to maintain shape after repeated use.

Our swimwear fabric

SwimZip uses advanced-performance fabrics that protect you during swimming, surfing, and beach play. Our quick-drying, lightweight materials pull water away from your skin to keep you comfortable in the waves or on the beach. These innovative fabrics resist damage from chlorine, salt water, and sun exposure.

UPF 50+ protection defines our fabric technology. This sun barrier blocks 98% of harmful UVA and UVB rays to reduce your risk of sunburn, premature aging, and skin cancer during outdoor activities.

Four-way stretch fabric moves with every twist, reach, and swim stroke. The material flexes and recovers without losing shape, so you never need to tug or adjust your suit. You get complete freedom of movement for volleyball or sandcastle building.

Our breathable fabric construction retains heat for chilly morning swims and cool beach days. The materials create a thin insulating layer of water against your skin in cold conditions. Strong seams and snag-resistant fibers prevent tears, maintaining the suit's protective properties through multiple seasons.
