Swimming during pregnancy is not only safe for most expecting mothers — it’s also highly recommended by health professionals for its numerous physical and emotional benefits. But as your body changes, so do your clothing needs, especially when it comes to swimwear. A pregnancy swimsuit, also known as maternity swimwear, is specifically designed to support a growing baby bump, offer gentle compression where needed, and keep you comfortable in the water. Whether you’re planning to take prenatal swim classes, relax at the beach, or stay active, the right maternity swimsuit makes all the difference. In this guide, we’ll explore everything from choosing the perfect fit to the latest swimwear trends for pregnant women in 2025, ensuring you stay stylish, supported, and confident throughout your pregnancy.
What is a Pregnancy Swimming Suit?
A pregnancy swimsuit, also known as maternity swimwear, is a specially designed swimsuit that accommodates a growing baby bump while providing the support and flexibility needed for pregnant women. These swimsuits are crafted from stretchy, breathable fabrics and often include additional features such as built-in bras, ruching, adjustable straps, and extra lining to ensure comfort and security during swimming or water aerobics.
Why Pregnant Women Need Special Swimwear
Pregnancy causes significant changes to a woman’s body — including breast enlargement, expanding hips, and, of course, the growing belly. Traditional swimwear often lacks the adaptability and comfort needed during these changes. Maternity swimsuits provide:
Optimal Comfort: Stretchy, breathable materials designed to move with your body.
Built-In Support: Reinforced bust support and belly coverage.
Style Confidence: Trendy designs that allow women to feel beautiful and confident.
Health & Safety: Full coverage and secure fits reduce discomfort and exposure to harmful UV rays or infections in public pools.
Types of Pregnancy Swimming Suits
One-Piece Maternity Swimsuits
Great for full belly and bust support. Look for versions with ruching at the sides to accommodate the growing bump.
Tankinis
Offers two-piece flexibility with full coverage. Easy to put on and take off, especially useful during bathroom trips.
Bikinis for Pregnancy
Modern maternity bikinis feature wide waistbands and supportive tops. Popular with moms who want minimal coverage and maximum comfort.
Swim Dresses
Perfect for extra modesty. These features are built-in shorts and provide more coverage for thighs and hips.
Maternity Wetsuits or Rash Guards
Ideal for surfing or cool-water activities. They provide extra insulation and protection.
2025 Maternity Swimwear Trends
As of 2025, several exciting trends are shaping the maternity swimwear market:
Sustainable Fabrics: Eco-conscious brands are using recycled nylon and organic materials.
Bold Prints: Animal prints, tropical florals, and color-block designs are popular.
UV Protection: Built-in SPF 50+ protection is becoming standard in premium swimsuits.
Inclusive Sizing: Brands now offer extended sizing (XXS to 5XL) to accommodate all body types.
Nursing-Friendly Designs: Some swimsuits now come with discreet panels for breastfeeding.
How to Choose the Right Pregnancy Swimming Suit
Step 1: Know Your Needs
Activity Type: Are you swimming laps or lounging at the beach?
Support Needs: Look for adjustable straps and built-in bras if you need bust support.
Style Preference: Choose something that reflects your personality.
Step 2: Choose the Right Fabric
Opt for fabrics with high spandex (Lycra) content for stretch and durability.
Check for quick-dry and chlorine-resistant materials.
Step 3: Get the Right Size
Avoid sizing up in non-maternity suits — choose actual maternity wear with bump space.
Use brand-specific sizing charts and measure your bust, underbust, and hips.
Step 4: Look for Must-Have Features
Ruching for belly expansion
Adjustable straps
Removable padding
UV protection
Lined gussets for hygiene
Practical Tips for Swimming During Pregnancy
Swimming is one of the safest and most recommended exercises during pregnancy. Here are some expert-backed tips:
Stay Hydrated: Drink water before and after your swim.
Avoid Hot Pools: Keep pool temperatures under 100°F to avoid overheating.
Watch Your Balance: Hormonal changes affect balance. Be cautious on wet surfaces.
Supportive Footwear: Wear slip-resistant sandals or pool shoes.
According to the American College of Obstetricians and Gynecologists (ACOG), swimming is one of the best physical activities during pregnancy due to its low-impact nature and full-body benefits.

FAQs
When should I start wearing a maternity swimsuit?
Most women switch to maternity swimwear during the second trimester (around 14-20 weeks) when the belly begins to grow noticeably and regular suits feel restrictive.
Can I wear a regular swimsuit while pregnant?
You can during early pregnancy. However, as your body changes, a regular swimsuit may become uncomfortable, tight, or unsupportive, especially around the bust and belly.
Are pregnancy swimsuits safe for the baby?
Absolutely. Maternity swimsuits are designed for comfort and support without any harm to the baby. Just avoid hot tubs or poorly maintained pools.
What fabric is best for Pregnancy Swimming Suit?
Look for blends like nylon-spandex or polyester-spandex with 4-way stretch. Recycled eco-friendly materials (like ECONYL) are also great and safe.
How many maternity swimsuits do I need?
One is enough if you swim occasionally. If you’re regularly attending prenatal water aerobics or swim classes, 2-3 suits ensure you always have a dry option.
