Let me tell you something: when you're pregnant and plus size, shopping for a swimsuit can feel like a cruel joke. The maternity section offers a handful of stretched-out options in sad beige, and the plus-size racks seem to forget that growing bellies exist. But I promise you, a **plus size maternity swimsuit** that makes you feel beautiful and comfortable is out there. I spent last summer testing over a dozen styles—from Target to Torrid to dedicated maternity brands—and I'm sharing the ones that actually worked.
First, let's talk about what to look for. A **plus size maternity swimsuit** needs to do three things: support your bust, accommodate your growing bump, and flatter the rest of you without squeezing in all the wrong places. The best fabrics are thick, chlorine-resistant blends with at least 20% spandex—they hold their shape and don't go see-through when wet. And please, avoid anything with a flimsy lining. You deserve better.

The Anatomy of a Great Plus Size Maternity Swimsuit
I tried a one-piece from **Lands' End** that had a subtle ruched side panel—not just for style, but for growth. This **plus size maternity swimsuit** came in sizes up to 26W, with a built-in shelf bra that actually supported my 40DD bust. The secret? The ruching is adjustable via a hidden drawstring, so you can loosen it as your bump expands. Another standout was the **Maternity Tankini from Torrid**—a two-piece set that lets you mix and match sizes. I wore a 3X top with a 4X bottom, and the side ties on the bottoms allowed for a customized fit. For moms who prefer bikinis, **Asos Curve's maternity line** has a high-waisted bottom with a crossover front that sits beautifully under the belly while still covering the lower back.
But fit isn't everything. Color and pattern matter too. I'm a firm believer that a bold print or a rich jewel tone can lift your mood instantly. My favorite **plus size maternity swimsuit** this season is a deep emerald green one-piece from **Motherhood Maternity**—it has a wrap-front detail that creates a flattering neckline, and the color makes me feel like a mermaid queen. Don't be afraid of stripes; just make sure they're diagonal or vertical, not horizontal, to create a lengthening effect.
How to Make Your Swimsuit Work for You
Let’s talk about the little details that turn a good swimsuit into a great one. First, straps. Thin spaghetti straps dig into your shoulders, especially when you’re carrying extra weight. Look for **plus size maternity swimsuit** styles with wider straps, halter necks, or even a built-in keyhole back for support. Second, tummy control panels can be a blessing if they’re not too tight. The **Honeylove maternity swimsuit** uses a soft compression panel that smooths without squeezing—perfect for those days when you want a little extra confidence. Third, consider the leg cut. A moderate or high-cut leg elongates your silhouette, while a boy short bottom provides more coverage. I prefer the high-cut because it balances my hips and lets me move freely.
Now, here’s a tip I learned from my sister, who is a yoga instructor: **buy a plus size maternity swimsuit** that fits you *now*, not one you hope to grow into. You can always add a wrap or a sheer cover-up for modesty. And if you’re between sizes, always size up. A too-small swimsuit will roll up at the thighs and dig into your shoulders, and that’s the last thing you need when you’re already dealing with swollen feet and backaches.

Real Options for Real Women
I’ve rounded up a few of my top picks, but remember: your body is unique, and what works for me might not work for you. That said, here are three **plus size maternity swimsuit** brands that consistently get it right:
- **Seraphine**: Their ruched one-piece comes in sizes up to 22 and has a removable belt that doubles as a belly band. The fabric is soft and stretchy, and the price hovers around $120—worth it for the quality.
- **Youswim**: This is a one-size-fits-most brand (up to size 24) that uses a clever knot system. You can tie it as a one-piece, a bikini, or a high-neck style. It’s not traditional maternity, but the fabric has enough give to accommodate a growing bump. Plus, it’s reversible!
- **Target's Ingrid & Isabel line**: Affordable and reliable. I tried their empire-waist tankini for $49.99, and the built-in shelf bra was surprisingly sturdy. The bottoms have a wide elastic waistband that stays put.
The Emotional Side of Buying a Maternity Swimsuit
I’d be lying if I said finding a **plus size maternity swimsuit** was only about fabric and fit. For me, it was about feeling seen. After months of watching my body change in ways I didn’t always welcome, standing in front of a three-way mirror in fluorescent lighting was… vulnerable. But when I slipped into that emerald green one-piece and saw the way the ruching cradled my belly like a gentle hand, I felt a quiet sense of peace. You don’t need to shrink to shine. Your body is doing something extraordinary, and it deserves a swimsuit that honors that.
So take your time. Order a few options, try them on at home with your favorite music playing, and return the ones that don’t spark joy. You’ll know the right **plus size maternity swimsuit** when you feel it—not because it hides your belly, but because it celebrates it.
