Kimjun 8.75 Yes Yes Yes

After weeks of testing various toddler swimwear for summer outings, this flamingo stripe one-piece from KIMJUN stands out as a reliable choice for active little ones. The blend of 80% nylon and 20% spandex provides a soft, stretchy fit that moves easily during pool play or garden activities. I was particularly impressed by how quickly the fabric dries, which is a lifesaver when transitioning from the beach to a car ride. The UPF50+ sun protection adds an essential layer of safety for sensitive skin during outdoor excursions. It strikes a perfect balance between a cute, stylish design and a functional rash guard that handles splashes and sun with ease.

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.
