CHYRII 9.80 Yes Yes Yes

Most beachwear options force you to choose between modest coverage and high-fashion edge, but this CHYRII monokini refuses to compromise on either. I was immediately struck by the intentionality of the design, which combines a deep plunging V-neckline with daring hollowed-out cutouts and a cheeky Brazilian-style bottom. The double nylon fabric feels exceptionally smooth against the skin, offering a level of stretch that makes it comfortable enough for all-day tropical lounging. While the lace-up back and adjustable straps provide a customizable fit, the removable soft cups ensure you have the right amount of support. It is a sophisticated, high-cut piece that feels specifically engineered for making a statement at the pool or on a summer holiday.

The neon green hue of this CHYRII monokini practically glows against sun-kissed skin, making it an instant standout for any tropical getaway. I was immediately struck by the tactile quality of the double nylon fabric. It feels incredibly smooth and offers a substantial stretch that moves with you rather than pulling. The design is unapologetically bold, featuring a deep plunging V-neckline and intricate lace-up details that transition into a striking low, backless silhouette. Because it incorporates a high-cut, cheeky Brazilian line and strategic hollowed-out cutouts, it manages to look high-fashion while remaining functional for pool lounging. The adjustable straps and removable soft cups allow for a more customized fit, ensuring you feel secure while embracing such a daring, stylish aesthetic.

Why settle for a basic bikini when you can command the entire poolside with a single look? The CHYRII Monokini is designed for the woman who wants to balance high-fashion edge with summer comfort. I found the seamless, elastic fabric feels incredibly soft against the skin, which is a huge plus when you are spending hours under the sun. The standout feature is definitely that adjustable zipper front paired with a plunging V-neck and a daringly low back. It creates a striking silhouette that works perfectly for tropical vacations or a chic beach day. Since it features a high-cut thong style, it really emphasizes your curves while keeping things breezy and lightweight for those hot holiday trips.

The combination of the sexy plunge V-neck and the low-back design creates a striking aesthetic that transitions perfectly from the pool to the seaside. With its high-cut fit and functional zipper front, it manages to be both chic and daring without sacrificing the ease of movement needed for a day in the sun.

Most people assume a high-waisted swimsuit is designed for modesty, but this CHYRII monokini uses that silhouette to actually highlight your curves through strategic cutouts. The criss-cross, strappy design turns a standard one-piece into a total showstopper for your next tropical vacation. I found the fabric to be incredibly smooth and seamless, offering a high degree of stretch that feels soft against the skin rather than restrictive. It features removable padding to help with the push-up effect, though there is a major sizing catch you need to know. Because the bust area runs quite large and the material is super elastic, you should definitely consider ordering one size down if you don't have a full bust to ensure a secure fit.

What We Like
Removable padding
High waisted cut
Criss-cross straps

Frequently Asked Questions

Quick answers about 18 Swimwear before you buy.

Always check the specific brand's size chart, as swimwear sizing varies significantly between manufacturers. If you are between sizes, we generally recommend sizing up for better comfort and less digging into the skin.

Chlorine-resistant fabrics are treated or woven with specialized fibers like PBT to prevent the material from thinning or losing shape due to pool chemicals, making them ideal for frequent lap swimmers.

Rinse your suit in cool, fresh water immediately after use to remove salt, chlorine, or oils. Avoid machine washing and harsh detergents. Instead, hand wash with a mild soap and air dry in the shade.

Look for swimwear with a UPF (Ultraviolet Protection Factor) rating. Fabrics with a higher UPF rating provide a physical barrier against harmful UV rays, offering better protection than standard synthetic blends.

Opt for suits with a double lining or a high-density fabric construction. Avoid very light-colored suits in thin materials, as they tend to become translucent when wet.

Absolutely. Modern one-piece designs have evolved into high-fashion pieces with cut-outs, bold patterns, and athletic silhouettes that work perfectly for both lounging and active swimming.

For activities like surfing or water aerobics, prioritize secure fits such as racerback tops, high-waisted bottoms, or drawstring ties to ensure the suit stays in place during movement.

All swimwear will experience some degree of stretching, but high-quality suits made with elastane or Lycra retain their shape much longer. Following proper care instructions is key to preventing permanent sagging.
