Can I return a swimsuit if it doesn't fit?
Yes — SwimOutlet offers returns on swimwear as long as the hygiene liner is intact and the swimsuit hasn't been worn in water. We recommend trying swimsuits on over underwear with the liner in place. If you're unsure about sizing, order two sizes and return the one that doesn't work.
How do I choose the right swimsuit for my body type?
The best swimsuit depends on what you want to highlight and what support you need. For midsection smoothing, look for one pieces with ruching or built-in tummy control panels. For bust support, underwire bikini tops and molded cup tankini tops provide structure. High waisted bottoms elongate the torso and create a flattering waistline. Swim dresses offer the most coverage with a feminine silhouette. If you're between sizes, consider swim separates where you can mix different sizes for top and bottom.
What sizes do your women's swimsuits come in?
Our women's swimwear collection ranges from XS to 3XL in standard sizing. Our plus size swimwear collection extends from size 16 through 26 (1X to 4X). Many one piece swimsuits are available in long torso and petite lengths. Bikinis and swim separates let you choose different sizes for top and bottom. Each product listing includes a brand-specific size chart — sizes vary by brand, so check the chart before ordering.
What's the difference between swimwear fabrics — which lasts longest?
Swimsuit fabric matters most if you swim regularly. Polyester blends marketed as "chlorine resistant" last 5–10 times longer than standard nylon-spandex in chlorinated pools — brands like Sporti, Speedo Endurance, and TYR Durafast use these fabrics. For beach and occasional pool use, standard nylon-spandex blends are softer, more comfortable, and perfectly fine. Always rinse your swimsuit in cool fresh water after every wear, and never put it in the dryer.
What's the most popular style of women's swimsuit?
One piece swimsuits are consistently the most popular women's swimsuit style, followed by bikinis and tankinis. One pieces offer the most versatility — they work for lap swimming, beach vacations, water parks, and everyday pool use. Within one pieces, tummy control styles and cut-out designs are trending. For beach and resort wear, high waisted bikinis and bandeau tops are top sellers.
