Women's One Piece Swimsuits: The Perfect Blend of Style and Support

SwimOutlet carries women's one-piece swimsuits for lap swimming, water fitness, beach, and resort wear in standard sizes 4 through 32 and plus sizes 18W through 26W. Styles range from performance training suits and conservative modest cuts to fashion styles with low backs and open backs, plus long-sleeve zip-front one-pieces for sun protection.

Necklines and Back Styles
Necklines available: scoop neck, square neck, sweetheart, V-neck, surplice, wrap, high neck, and plunge. Back styles include scoop back, crossback, racerback, low back, open back, and zipper-front. Crossback and racerback styles stay in place through active swimming. Low-back and open-back cuts suit resort and beach use over lap swimming. See women's swimwear for the full catalog across all styles.

Chlorine-Resistant and Performance Fits
A large share of styles use chlorine-resistant fabric (primarily 100% polyester or Nylon/Lycra Xtralife) built to hold color and shape through daily pool use. Performance and active fits run compressive and close to the body for lap swimming and water fitness. Conservative fits offer fuller seat coverage and higher necklines for a more modest silhouette. Tummy-control panels and removable cup options are available in multiple styles. See women's competition and training swimwear for the full athletic-cut range.

UPF 50+ and Long-Sleeve Styles
Many styles carry a UPF 50+ sun protection rating. Long-sleeve zip-front styles add arm coverage for open-water swimming, outdoor pool sessions, and beach days where sun exposure runs long. Fabrics include recycled polyamide and recycled polyester blends from several brands. Prices run from under $15 to $182, with most styles between $35 and $85.
