What to Look for in a Maternity Swimsuit

Comfort

Webster says comfort is most important when shopping for a maternity swimsuit, from one-pieces to two-pieces. “Many styles also work great for postpartum,” she tells Byrdie, suggesting a suit with an easy pull-down or clip-down access if you’re planning to breastfeed as a money-saving hack. Once you’ve determined if a one or two-piece maternity swimsuit is your ideal style, the designer says to focus on other features like neckline—such as V-neck or a scoop—and smaller accents such as ruffles, hardware, and bow-ties. “If you’re into two-piece suits, decide if you want a bikini top or tankini top and if you want high-rise bottoms or low-rise bottoms,” she continues. “High-rise bottoms should have gathered at the side to accommodate a bump, and low-rise bottoms will fit just under your bump.” 

Material

Material is also important when shopping for maternity swimsuits. “Now is not the time for tight and constricting fabrics,” Webster notes. Instead, the designer says four-way stretch fabrics are best, including seersucker and gathered detailing, which allow a swimsuit to grow with you and fit you during many stages. “Some suits use a recycled polyester, a great eco-friendly option,” she adds. It’s also a good idea to choose fabrics with UPF 50+ to protect against UV rays, reducing your exposure to the sun.

FAQ
  • Do you need a maternity swimsuit?

    “A maternity swimsuit is essential because it’s specifically designed to accommodate changes in size,” says Webster. “Sizing up in a traditional swimsuit will often give you an awkward fit; it might be tight in some places and loose in others. Maternity swimwear is carefully designed with stretchier materials and cuts to fit you in all the right places.”

  • How should a maternity swimsuit fit?

    “A maternity swimsuit should fit comfortably and not feel too tight or too loose, especially in the tummy and bust area, as those are the areas changing the most,” explains Webster. “If you’re purchasing a swimsuit in the first or second trimester, make sure there’s enough room in the bust and tummy,” she continues. It’s also essential to avoid a suit that’s too loose and gaping, especially at the leg openings towards the end of your pregnancy.

  • What makes a maternity swimsuit different than a regular swimsuit?

    According to Webster, “Maternity swimsuits have additional room in the tummy and either use stretchier fabrics (like crinkle or seersucker) or have additional gathers at the sides," allowing plenty of room to grow while feeling comfortable and flattering postpartum. “A good maternity swimsuit also has additional bust support to support changes in bust size during pregnancy and postpartum,” she adds. “Look for styles with built-in bras, removable padding, and straps that can be adjusted for better support.”
