Racerback Swimsuit High Cut - Red / Pink

Start with your activity and personal comfort. If you’ll be ducking under waves or doing dynamic water sports, a one-piece with a secure racerback or cross-back will stay put best​. For long swimming sessions or surfing, you might prefer higher necklines or sleeves for extra coverage (and sun protection). If you’re mostly lounging or casual swimming, you can explore stylish cuts like high-leg openings, zippers, or bold prints – just make sure the suit still supports your bust and bottom comfortably. WALLIEN offers everything from sleek athletic designs to chic color-block styles, so you can pick a silhouette that matches your performance needs and personal taste. The right style is the one that makes you feel confident, supported, and ready for fun in the water.

The best swimsuits use high-performance, stretchy fabrics that can stand up to sun, salt, and chlorine. WALLIEN one-pieces, for example, are crafted from premium Italian recycled nylon (made from reclaimed ocean plastics) blended with Lycra® for stretch​. This means our suits are not only eco-friendly but also exceptionally soft, quick-drying, and durable. Look for materials labeled as chlorine-resistant if you’ll swim in pools frequently – these resist fading and fiber breakdown. Quality fabric should offer 4-way stretch to move with you and snap back to shape, so your suit doesn’t bag out. Bonus: our Italian fabric even provides UPF 50+ sun protection​, proving that sustainable material can deliver top-notch performance and longevity.

Yes – a quality one-piece will absolutely support your bust. Many one-piece swimsuits (like ours) come with built-in shelf bras or supportive lining to keep your chest secure during movement. WALLIEN’s designs feature integrated bust support, and our customers rave that the suits are “flattering” and “stay in place perfectly”​. Unlike some bikinis, a well-made one-piece won’t shift around, so you can dive, surf, or swim laps with confidence. For larger busts or high-impact activities, look for styles with thicker straps, higher necklines, or even zip fronts for added security. In any case, you’ll get full coverage and a worry-free fit around the bust in a one-piece, without sacrificing style.

Your one-piece should fit snugly and feel supportive but still comfortable. Look for a “second-skin” fit – the fabric should mold to your body without any sagging or gapping, and straps or seams shouldn’t dig in​. When you move, nothing should slip out of place. Our WALLIEN suits are tailored to the female form for exactly this reason, balancing a close fit with soft stretch so you get support without that stranglehold feeling. If you’re between sizes (or have a longer torso), consider sizing up for a better length and comfort – a properly fitting one-piece gives you confidence to dive in and perform, no distractions.

To keep your swimsuit looking and performing like new, rinse it in cool fresh water after each swim. This washes out salt, chlorine, and sunscreen that can otherwise dull the color or weaken the fabric​. It’s best to avoid washing machines or harsh detergents – even gentle machine cycles can damage swimwear fabric and fade colors​. Instead, hand wash with mild soap if needed. Gently squeeze out water (don’t wring it like a towel) and lay your suit flat to dry in the shade, which helps it maintain its shape and elasticity​. Also, try to avoid rough surfaces (like sitting directly on concrete pool decks) to prevent snagging the material. With a little TLC – quick rinses, gentle washing, and flat drying – your one-piece will stay vibrant and ready for many seasons of adventures.

Definitely. One-piece swimwear is a top choice for lap swimming and competitive training because it’s streamlined and stays in place. Performance one-pieces minimize drag in the water​, helping you glide through your strokes faster. WALLIEN’s one-piece suits use compressive, race-back designs that hug your body like a second skin for optimal speed. They’re also ultra chlorine-resistant​, so daily pool sessions won’t fade or break them down. In short – if you’re hitting the pool for serious swim workouts, a quality one-piece will support your endurance and style.

Absolutely. Modern one-piece swimsuits are ideal for active water sports like surfing, paddle boarding, and diving. Unlike bikinis, a well-designed one-piece stays put through duck dives and wipeouts, so you won’t be adjusting your suit mid-session​. WALLIEN one-pieces are co-created with water athletes for a secure, performance-driven fit – meaning you can focus on catching waves or doing laps, not on wardrobe malfunctions. These suits give you full range of motion and confidence, whether you’re carving up a wave or diving for a volleyball.

One-piece swimwear offers enhanced coverage and support, making it ideal for active water sports and everyday wear. Its streamlined design minimizes drag, while modern cuts and eco-friendly fabrics ensure both comfort and style.

The key to feeling great in a one-piece is finding a cut that complements your shape and highlights what you love. Fortunately, one-pieces come in many silhouettes. If you want to accentuate your waist, try a style with color-block panels or a belt detail. For more bottom coverage or a curvier look, a boyshort or retro high-waist cut can be very flattering. High-cut leg openings will elongate your legs, while a plunging neckline or open back can add a bit of glam. It really comes down to what makes you feel confident. WALLIEN focuses on designs that celebrate the female form – our suits have thoughtful seaming and stretch that hug in all the right places without pinching. Remember, confidence is the most stylish thing you can wear. When you’re comfortable and supported in your swimsuit, you’ll automatically stand taller and shine brighter. So choose a quality one-piece that fits well and aligns with your style, and you’ll always look fabulous by the water.

Yes – sustainability is at the heart of WALLIEN. Our one-piece swimwear is made with eco-friendly materials like recycled plastics (including reclaimed fishing nets and plastic bottles) to help reduce ocean waste. We craft each suit to be high-performance and long-lasting, so you can enjoy your water sports knowing you’ve made a greener choice for the planet.

For a perfect fit, refer to our detailed sizing guide and consider your measurements carefully. A well-fitted one-piece should hug your curves without feeling restrictive, allowing for maximum mobility and confidence in the water.

UPF 50+ is a Ultraviolet Protection Factor rating that means the fabric blocks 98% of the sun’s UV rays​. In simpler terms, a swimsuit with UPF 50+ acts like additional sunscreen built into your suit. If you’re swimming or surfing outdoors, UPF swimwear is a smart choice to help protect your skin (especially on areas like your back and shoulders that get full sun exposure). WALLIEN incorporates UPF 50+ into our one-piece swimsuits as a standard, so you can play under the sun longer with less worry. Of course, you should still use reef-safe sunscreen on exposed skin, but a UPF-rated suit gives you that extra layer of defense against sun damage. For any water woman who spends hours outside, UPF protection in swimwear is a big benefit and highly recommended.

For triathlons, choose a one-piece swimsuit designed for performance and comfort. Look for features like a racerback design for maximum range of motion, quick-drying and moisture-wicking fabrics, and a sleek, minimal chamois for comfort during the bike segment without adding bulk during the swim and run. These features ensure optimal swim performance, flexibility, and comfort throughout the race.

Yes, one-piece swimsuits provide excellent coverage and support, making them ideal for various water sports such as surfing, kayaking, kite surfing, and paddle boarding. Their streamlined design minimizes drag and allows for unrestricted movement, enhancing your performance in these activities.
