How to Choose a Maternity Swimsuit: Stylist's Advice

Seven months pregnant, my client Anna, the CFO of a major IT company, was standing in the fitting room of a specialty store, close to despair. She was about to have a babymoon on the Amalfi Coast, and all the selection offered were infantile tankinis with tiny floral prints and shapeless robes with oddly gathered details. "Camilla, have my taste and status really disappeared with the appearance of my belly?" she asked me over video call. Of course not.

Choosing swimsuit for pregnant women Women make the same mistake time and time again—they head to the "maternity" section. But the reality is, you don't need to buy clothes for two months and then hide them on the back shelf forever. We've already covered the concept of an adaptive wardrobe in more detail in our The complete guide to stylish maternity clothes Today, we'll explore the beach capsule collection: how to create a luxurious poolside look using the right fabrics and precise cuts from premium lines.

Maternity Swimsuit: Why I Often Discourage You From Buying One

According to statistics, approximately 80% of specialized maternity beachwear on the mass market is made from the cheapest polyester. Manufacturers rely on quick turnover: the item is only needed for a short period of time, meaning they can skimp on the quality of the raw materials. The result is a "granny" cut, flimsy plastic hardware, and prints that visually cheapen the look.

My contrarian insight, which I repeat to all my clients: a regular, high-quality swimsuit made from technical, stretchy fabrics outperforms specialized models in every way. By investing €150–200 in a minimalist style from brands like Hunza G or the premium COS line, you're getting a piece that will fit your changing figure luxuriously now and return to its original size after childbirth. This isn't just about saving money; it's about preserving your appearance.

Anna and I ended up choosing an asymmetrical black swimsuit from the regular collection. It accentuated her shoulders, softly hugged her belly thanks to the textured fabric, and became her favorite piece even a year after the birth of her child.

Fabric Architecture: What to Look for on the Label to Avoid Disappointment

During pregnancy, your blood volume increases, and your core body temperature rises slightly. Forget cheap polyester—it instantly creates a greenhouse effect in the sun. If you read our article about summer business style clothing for women in the heat , you know how important hygroscopicity is.

• Correct composition: Look for a combination of polyamide (nylon) and at least 15–20% elastane (spandex/lycra). Polyamide cools the skin, dries faster, and resists fading, while the high percentage of elastane provides the necessary support without constriction.
• Crinkle technology (header): This is your main ally. In my studio, I often demonstrate the difference: classic smooth biflex fabric, when pulled tightly on the stomach, becomes thinner and digs into the skin at the edges. The presser, on the other hand, works like an accordion—the fabric opens to the exact desired volume, maintaining its density and not constricting lymph flow.
• UPF 50+ rating: According to the Skin Cancer Foundation, up to 70% of women experience melasma (the "mask of pregnancy") due to hormonal fluctuations. Fabric with UPF 50+ protection isn't a marketing ploy, but a dermatological necessity for preventing persistent pigmentation.

Top 3 Trendy Silhouettes: Translating Runway Trends into Comfort

According to the WGSN analytical report (2024), beachwear is finally saying goodbye to overly cluttered decor, returning to the aesthetics of "quiet luxury" and the minimalism of the 90s. This is ideal news for pregnant women: clean lines work much better than attempts to drape volume.

Asymmetrical one-shoulder models

Asymmetry is a brilliant architectural technique. The diagonal line across the chest visually elongates the silhouette, creates dynamism, and draws attention away from the heavy hem. It looks elegant and very mature.

"A technical detail I always check during fittings: the strap width on an asymmetrical swimsuit should be at least 4 centimeters. A thin strap won't provide the necessary support for a growing bust and will leave a painful red mark on your shoulder by the end of the day."

V-neck bikini bottoms

It's time to dispel the stereotype that pregnant women should only wear one-piece swimsuits. A two-piece swimsuit is often much more comfortable. Choose under-bump swimsuits (straight under the belly) with a V-neck. This is the most anatomically correct option—the elastic band doesn't put pressure on the uterus in any position, and the V-neck visually lengthens the legs.

Bandeau with accent details and a high waist

A retro, Grace Kelly-inspired aesthetic is perfect for the first two trimesters. High-waisted bottoms, made of thick (but not compression!) fabric, provide a subtle, put-together feel. But there is an important limitation here: This advice is absolutely ineffective during the third trimester. As your belly drops, any elastic band in the middle will roll down and cause discomfort.

Cutting Mistakes: What Details Instantly Cheapen a Beach Look

When creating a capsule, it's important to understand not only what to buy, but also what to categorically avoid. In the article How to Look Expensive: Secrets of a Status Wardrobe We discussed how unnecessary details ruin a look. On the beach, this rule applies with double force.

• Side assemblies (ruching): A classic trick used by maternity brands. Yes, they provide some extra fabric for the belly, but they create a visually appealing caterpillar effect and are hopelessly outdated. A smooth, stretchy fabric would do the job much more elegantly.
• Excessive decor: Ruffles, frivolous bows at the hips, and built-in skirts are a surefire way to make a grown woman look childish. Save them for children's swimsuits.
• Spaghetti straps: As your bust size increases to CD and above, the laces throw off your proportions—your breasts appear even larger, and the laces themselves dig into your neck, causing a migraine by the end of your beach day.
• Prints: Avoid small florals and tropical "porridge." According to the laws of composition, a small pattern on a large area (like the stomach) will stretch and distort the figure. Your choice should be deep monochrome shades (chocolate, olive, terracotta, black) or a strict color block.

Status Styling: How to Create an Expensive Look Around a Swimsuit

A swimsuit is just the foundation. The layers you layer over it really make the look luxurious. Forget those translucent synthetic pareos in acidic shades.

One of my favorite styling tricks for shoots is wearing a men's linen shirt that's two sizes too big. Pick up a classic white or light blue linen shirt (around 180 g/m²) from the men's department at Zara or Massimo Dutti (budget €40-60). Throw it over a minimalist swimsuit and casually roll up the sleeves, creating just the right amount of structure, keeping the sun off your shoulders, and allowing you to move freely.

Complete the base with status accessories. As we already mentioned in the article about status accessories The devil is in the details. Swap your canvas beach bag for a stiff, woven raffia tote. Add chunky tortoiseshell sunglasses and a wide-brimmed straw hat with a stiff brim. The "three-layer" rule (swimsuit + cover-up + accent accessory) instantly elevates you from "just going for a swim" to "vacationing at the villa" status.

Pre-purchase checklist: Test for the perfect fit (Action Plan)

So, you're in the fitting room. Before you cut off the tags, try this quick four-step test:

1. Tension test (memory effect): Stretch the fabric slightly at the waist and release. If it returns to its original shape slowly or becomes wavy, leave it in the store. High-quality elastane regains its shape in a split second.
2. Checking the seams: Run your finger along the inner seams. They should be flatlock or completely hidden within the fabric. During pregnancy, skin is prone to dermatitis, and any rough seam will be a real pain in the ass in the heat.
3. Armhole Rating: High-leg cutouts (high on the thigh, '80s style) are trending right now. However, for the third trimester, I recommend a classic mid-cut. An overly high hipline will constantly shift with your shifting center of gravity, forcing you to tug at your swimsuit.
4. Forward bend: Be sure to lean forward at a 45-degree angle. Your chest shouldn't be hanging out, and the straps shouldn't fall off your shoulders.

To avoid buying unnecessary items before your vacation, I strongly recommend digitizing your beach wardrobe. Using the smart wardrobe feature in MioLook app , you can upload photos of a swimsuit, shirt, flip-flops, and hat to create 5-6 ready-made looks in advance and avoid having to carry half your closet with you.

Choosing beachwear while expecting a baby is a great way to practice accepting your new body. Don't try to hide your belly with childish ruffles or specialized covers. Opt for refined textures, deep colors, and clean lines from premium lines, and you'll feel your confidence return along with comfort.
