EKOUAER Maternity Swimsuit vs Regular Swimsuit: What's the Difference?

A maternity swimsuit is built with extra fabric across the belly, adjustable support in the bust, and four-way stretch that accommodates your changing body throughout pregnancy, while regular swimwear is cut for a static figure and will quickly become uncomfortable as you grow. EKOUAER's maternity swimsuit collection addresses these needs with thoughtful construction that regular suits simply can't match.

We tested both styles across trimesters to show you exactly where maternity designs excel and why investing in pregnancy-specific swimwear makes pool days and beach trips genuinely comfortable.

How Maternity Swimsuit Fit Differs From Regular Cuts

The most obvious difference is belly room. Maternity styles feature a paneled front or ruched fabric that stretches vertically and horizontally, creating space without excess bulk. Regular swimsuits pull tight across your midsection by the second trimester, creating pressure and riding up constantly.

Torso length is the second critical distinction. Pregnancy adds inches to your torso as your ribcage expands and your belly grows. A maternity swimsuit one piece typically includes 2 to 4 extra inches in the body compared to the same size in regular swimwear, preventing that awkward too-short feeling.

Leg openings sit differently too. Maternity cuts angle the leg line to avoid digging into your hips, which widen during pregnancy. Regular high-cut styles that looked flattering pre-pregnancy often create uncomfortable pressure points by the third trimester.

Support Features You Won't Find in Regular Swimwear

Bust support becomes essential as your chest changes size multiple times during pregnancy. Maternity designs incorporate:

• Built-in shelf bras with wider bands that distribute weight
• Adjustable or convertible straps that let you customize lift
• Soft cups or removable padding that accommodate fluctuation
• Empire waistlines that provide under-bust definition without constriction

Regular swimsuits rely on static cup sizes and narrow straps that dig in as your bust grows. The tankini swimsuits style is particularly popular for maternity because the separate top lets you size each piece independently and offers easy access for nursing clothes functionality postpartum.

According to Forbes Vetted's maternity swimsuit guide, adjustable features rank as the top priority for pregnant swimmers because your body changes week to week.

Fabric and Stretch: Why Material Matters

Maternity swimwear uses fabrics with higher spandex content, typically 18 to 25 percent compared to 10 to 15 percent in regular suits. This extra stretch ensures the fabric moves with you rather than restricting circulation or creating uncomfortable compression.

The fabric weight is also lighter in quality maternity pieces. Heavy compression fabrics found in shapewear-style regular swimsuits can restrict belly movement and feel stifling when you're already overheated from pregnancy hormones.

Chlorine resistance matters more during pregnancy because you'll likely wear the same suit frequently over several months. Look for polyester-spandex blends rather than nylon, which breaks down faster with repeated pool exposure.

Maternity Swimsuit Two Piece vs One Piece Styles

Maternity swimsuit two piece options offer the most versatility. You can mix sizes (a common need when your belly and bust grow at different rates), and separates make bathroom breaks dramatically easier. A tankini pairs a longer top that covers your belly with bottoms that sit comfortably under your bump.

One-piece maternity suits provide more coverage and support if you prefer a secure feeling or want to minimize sun exposure on your belly. The downside is bathroom logistics, especially in public restrooms where you're maneuvering a wet suit in a small stall.

The maternity swimsuit shorts option combines bikini-style tops with boy-short or swim-short bottoms, preventing chafing between the thighs (a common third-trimester complaint).

Finding Your Size: Maternity Swimsuit Plus Size Considerations

Most maternity swimwear brands recommend ordering your pre-pregnancy size, as the designs already account for belly growth. However, maternity swimsuit plus size shoppers should pay attention to bust and hip measurements specifically, since these change independently of belly size.

If you're between sizes or your bust has increased two or more cup sizes, size up in one-piece styles. For two-piece options, size the top and bottom separately based on current measurements.

When to Switch From Regular to Maternity Swimwear

Most pregnant swimmers need maternity-specific suits by 14 to 18 weeks, though this varies based on your body and whether it's your first pregnancy. Signs it's time to switch include:

• Your regular suit creates a muffin-top effect above the waistline
• Straps dig into your shoulders or leave red marks
• You're constantly adjusting or pulling the suit down
• The fabric feels restrictive rather than supportive

You can extend the life of regular suits briefly with size-up shopping, but purpose-built maternity designs offer comfort worth the investment, especially if you swim regularly for exercise or relaxation during pregnancy.

Postpartum Wear: Do Maternity Suits Work After Birth?

Quality maternity swimwear transitions well into the postpartum period. The extra stretch accommodates your healing body, and styles with ruching or draping camouflage the belly area while your abdomen recovers. Nursing tops pair well with swim bottoms if you need breastfeeding access at the pool.

Tankini styles prove most versatile postpartum because you can lift the top for nursing without removing the entire suit. The same supportive features that worked during pregnancy (wide straps, shelf bras, gentle compression) continue to provide comfort as your body changes again.

Retailers like Old Navy's maternity swimwear collection and EKOUAER offer designs that intentionally bridge pregnancy and postpartum wear, maximizing your investment. Browse current styles and apply our discount code to save on suits that work for multiple stages.

Our Verdict: Is Maternity Swimwear Worth It?

If you'll swim more than a handful of times during pregnancy, maternity-specific swimwear delivers measurably better comfort and fit than regular suits. The targeted construction supports your changing body without restriction, and quality pieces like EKOUAER's maternity swimsuit line last through pregnancy and postpartum wear.

For occasional swimmers or those on tight budgets, a well-chosen maternity swimsuit two piece offers the best value since you can reuse the bottoms longer and replace only the top as needed. Skip regular swimwear a size up, which saves money initially but rarely fits well at any stage.
