Finding plus size maternity swimsuits can feel like an Olympic sport. You’re already navigating a body that’s changing week to week, and then you add the challenge of finding swimwear that actually fits a growing bump AND comes in plus sizes? The options narrow fast, the styles get less interesting, and the frustration can build quickly.
But here’s the truth: a great plus size maternity swimsuit exists. Several of them, actually. And finding the right one isn’t just a nice-to-have, it’s worth the search. Whether you’re planning a babymoon, spending weekends at the pool, or just trying to stay cool and comfortable, you deserve a swimsuit that makes you feel like yourself… bump and all.
What the Expert Says About Plus Size Maternity Swimwear
We turned to Jen McLellan, Certified Childbirth Educator and founder of Plus Size Birth, for her take. Jen is one of the leading voices on plus size pregnancy and maternity clothing, and her advice is always grounded and practical:
“When purchasing plus-size maternity clothes, getting a supportive (and cute) swimsuit is a must! Beyond the blissful relief of weightlessness, swimming and water aerobics are fantastic ways to engage in joyful movement during pregnancy. So while your current suit might last longer than you expect, if it gets snug, size up or invest in a maternity suit.”
That’s the perspective we’re working from. Not “here’s how to hide your bump” but here’s how to feel supported, comfortable, and genuinely good in the water.

Smart Tips for Shopping Plus Size Maternity Swimsuits
Before you shop, a few things to keep in mind that will save you time, money, and frustration:
Consider separates over one-pieces. When dedicated plus size maternity swimsuits are limited, shopping separate tops and bottoms in different sizes is a genuinely smart move. Your bump and your top may be two different sizes entirely and that’s completely normal. High-rise swim bottoms with power mesh (like the Torrid option above) provide real belly support even when they’re not technically maternity.
Shop secondhand first. Maternity clothes have the shortest wear window of almost any clothing category. Check Poshmark, Mercari, or ThredUp before buying new, you’ll often find brand new or gently used plus size maternity swimsuits at a fraction of the retail price. New and expectant parents sell these items quickly after delivery.
Bike shorts and swim shorts are valid options. They won’t hold up to chlorine as long as swimsuit-specific fabric, but plus size bike shorts (Yitty is a great starting point) can provide excellent belly coverage and support in a pinch, especially for lake days or beach trips where you’re not swimming laps.
Size up when you’re in between. Pregnancy bodies change fast. If you’re between sizes, go up, a suit that gives you room to grow is a far better investment than one that fits perfectly at 20 weeks and doesn’t work at 30.
Prioritize stretch and lining. Look for suits with substantial stretch and good lining, especially in the belly area. This matters more for comfort and fit than the specific style you choose.
