Neon plus-size swimsuits with UPF 50+ protection
Finally, UPF swimwear that fits right, supports every curve, and makes a bold, colorful statement.
Why choose our neon plus-size swimwear?
We get it. Finding plus-size swimwear for women that fits and flatters feels impossible. We create swimsuits for curvy women, sizes XL–3XL, who are tired of compromising on comfort, style, and safety.
No more pinching or digging
The problem: Your current swimsuit pinches, digs into your skin, or creates uncomfortable bulges.
Our solution: Soft, flexible materials with strategic seaming move with your body. No jagged wire, no digging, just comfortable support all day long.
Better bust support
The problem: Your bust falls out of your swimsuit, or you get zero support.
Our solution: Built-in push-up support with features like adjustable halter neck straps and secure construction. You can swim, play, and move confidently without constantly adjusting.
Tummy control without the frump
The problem: Your swimsuit makes your belly look unflattering.
Our solution: Modest plus-size swimwear, like high-waisted bottoms with tummy control panels, smooths your silhouette while keeping you stylish and trendy. Our hip minimizers create a flattering shape that celebrates your curves.
Match your family
Unlike other brands, we offer coordinating family swimwear. You can match your kids and partner instead of feeling left out of family photos. Browse our women's swimwear collection to coordinate with kids’ swimwear and men's swimwear. When you match your kids with neon, you make a bold statement and also keep them safe.
“This is my second Swim Zip in this style. I love it. Being in between a regular and a plus size, it's not just hard to find anything that will fit without swallowing me or being too small, it's nearly impossible to find anything that fits AND is anything close to fun and youthful.”—CC
High-visibility for safety and confidence
Water safety experts recommend neon colors because they're easy to see in crowded pools and beaches. Research shows that bright neon shades remain visible against light and dark pool bottoms, giving parents and lifeguards the ability to spot swimmers quickly.
Our neon pink, neon yellow, and neon lime green swimsuits keep you visible and looking amazing.
Coverage options that flatter your curves
Choose from full coverage options that make you feel most confident:
- One-piece swimsuits: Full coverage with front zippers for easy changing and a secure fit during activities.
- High-waist bikini sets: Two-piece options that let you mix and match sizes and styles for top and bottom to get your perfect fit.
- Long-sleeve options: Extended sun protection for arms and shoulders.
- Tankinis: Sophisticated looks with adjustable coverage options.
- Swim dresses: Elegant coverage with flattering A-line silhouettes.
All styles come in high-quality UPF 50+ fabric made from recycled polyester for durability and environmental responsibility. Research shows that UPF fabric blocks UV rays better than sunscreen. That’s why the Skin Cancer Foundation backs our fabric. When you wear SwimZip, you know you’re safe during long days outdoors.
When should I wear neon swimwear?
Our neon swimwear glows in situations and environments where you want to stand out:
- Beach volleyball and group sports for instant identification

How to get the right fit
Use our size chart to match bust, waist, and hip measurements with appropriate swimsuit styles.
When sized correctly, our neon one-piece swimwear and neon tankinis provide supportive bust construction, a secure waistband placement that prevents rolling, and comfortable leg openings that eliminate digging. A precise fit allows tummy control panels to smooth your silhouette while adjustable straps distribute weight evenly across shoulders for all-day comfort.
Styling bold neon swimwear
Neon swimwear makes the statement, so keep accessories complementary:
- Neon pink: Pair with white cover-ups and gold metallics for tropical sophistication
- Neon yellow swimsuit: Match with navy elements and denim for casual beach-to-street transitions
- Neon lime green: Combine with black accessories for an athletic, modern edge
Wide-brim sun hats in neutral tones add protection without competing. Our electric vibrant colors create memorable looks for family beach photos and social gatherings.
Plus-size swimsuits FAQ
What swimsuit is best for a big belly?
High-waisted bikini bottoms with tummy control panels work best for concealing a larger midsection. Full coverage one-piece swimsuits with ruching across the torso also flatter curvy women by smoothing the silhouette. Hip minimizers and supportive bust construction balance proportions, while maternity-friendly designs accommodate changing body shapes.
Is it better to size up in swimsuits?
Check our size guide using a measuring tape for accurate bust measurement, waist measurement, and hip measurements before ordering. Proper sizing allows tummy control features to work correctly and supports your bust.
Do swimsuits get tighter or looser when wet?
Swimsuits feel tighter when wet, since water adds weight and the fabric contracts. The support layer and push-up features can become slightly more compressed. Our chlorine-resistant materials maintain their shape better than standard fabrics.
How tight should your swimsuit be?
Your swimsuit should feel snug without digging into skin or creating bulges. Proper fit allows comfortable movement while maintaining the support layer integrity. Halter neck straps should distribute weight evenly, and waist belt features should sit flat against your body without rolling.
Do swimsuits shrink or expand over time?
Quality swimwear made from recycled polyester maintains its shape longer than cheaper alternatives. Four-way stretch construction resists shape changes, while frequent stretching can cause expansion. Chlorine-resistant fibers prevent breakdown and maintain elasticity through multiple swimming seasons.
