While maternity swim dresses offer full coverage and a classic silhouette, they’re not the only option for expecting moms. Many women prefer more flexible or minimal swimwear styles during pregnancy—especially when comfort, breathability, or easy bathroom access is a priority. In 2025, maternity tankinis and two-piece swimsuits are popular alternatives, blending style, practicality, and versatility. Let’s explore these chic options and how they compare to traditional maternity swim dresses.
1. Maternity Tankinis: Comfort and Coverage in One
Tankinis are a top choice for pregnant women who want the ease of a two-piece with the coverage of a one-piece. These swimsuits feature a tank-style top that extends over or slightly below the baby bump, paired with maternity bottoms that offer full belly support.
Key Benefits of Maternity Tankinis:
- Easy to put on and take off — especially helpful for restroom breaks.
- More breathable than a full dress or one-piece, keeping you cooler in warm weather.
- Mix-and-match potential with various top and bottom styles.
- Flattering fit with ruching or empire waists that grow with your bump.
2. Two-Piece Maternity Bikinis: Embrace the Bump
More moms-to-be are embracing their changing bodies with pride, and the maternity bikini reflects that confidence. Two-piece maternity bikinis typically include a supportive bra-like top with adjustable straps and high-waisted or under-bump bottoms for comfort and flexibility.
Why Choose a Maternity Bikini?
- Minimal fabric means faster drying and better movement in the water.
- Perfect for tanning or beach lounging, especially in the second trimester.
- Great for hot climates, providing relief from heat and humidity.
- Stretchy and forgiving materials accommodate rapid body changes.
3. High-Waisted Maternity Bottoms
Not all maternity two-pieces have to be skimpy. High-waisted bikini bottoms offer more belly coverage and support, making them a middle ground between full swim dresses and low-rise bikinis. These can be paired with longline tops, crop-style tankinis, or halter neck bras for a more balanced look.
4. Maternity Rash Guards and Swim Tops
If sun protection or modesty is a concern, maternity rash guards and swim tops are a smart alternative. These can be paired with bikini or tankini bottoms and are often made with UPF 50+ materials to shield your skin.
Advantages of Rash Guards:
- Added sun protection for shoulders, arms, and upper back.
- Stylish and athletic look, ideal for surfing or water sports.
- Postpartum-friendly, especially if nursing zippers or flaps are included.
5. Mix-and-Match Swimwear Sets
More brands are offering maternity-friendly separates, allowing you to mix sizes, colors, and patterns to suit your stage of pregnancy and personal style. This approach offers maximum flexibility—especially if your body is changing quickly or if you want multiple looks without buying full sets.
