Maternity swimwear has never looked better in Australia. From unmissable bikinis to supportive one-pieces, pregnancy bathers give you the confidence to get in the water with a bump on board … and look fabulous doing it.

Maternity swimwear is specially designed to fit and support growing bumps. Not only does it make beach and pool days that much more enjoyable, but with so many styles to choose from, expecting mums no longer have to sacrifice their style when it comes to swimming. Best of all, with features that include nursing pockets for breastfeeding, adjustable straps and stretch in all the right places, they’ll take you beyond pregnancy and right through the postpartum stage.

To take the fuss out of your maternity shopping, we’ve scoured the country and dug up Australia’s most-loved and stylish pregnancy swimsuits. But before we dive right in, here are some pointers to help you narrow down your search.

Top Tips For Buying Maternity Swimwear

Seraphine Nautical Tie-Back Maternity Bathers
Seraphine Nautical Tie-Back Maternity Bathers

When shopping for maternity swimwear, there are several things to consider and look for:

  • Comfort is key - Firstly, make sure the swimwear is comfortable and allows for ease of movement. It should also be flexible and supportive to accommodate your changing body shape.
  • Will you be breastfeeding? Many modern styles come with fold-down panels for easy feeding. So if you plan on feeding baby while poolside, a nursing swimsuit deserves a spot on your breastfeeding checklist.
  • Adjustable straps are a must - Look for bathers with adjustable straps to ensure the best fit. Remember, your body will be changing throughout your nine months of pregnancy, so you need to be able to adjust your swimmers to fit.
  • Need more coverage? There’s a style for that! - During pregnancy some women prefer a little more coverage than their usual bikini. If this sounds like you, consider a full one-piece, a tankini-style two-piece or even a swim dress.
  • Chlorine resistance - Lastly, if you’re after a swimsuit that will last beyond the babymoon, look for hardy, chlorine-resistant fabrics.

With a little more modesty than a standard one-piece, swim dresses are a godsend during pregnancy if you’re feeling self-conscious about your changing body. Designed to fall from under the bust, they offer great coverage of the bottom and thighs but pack some mighty big style points. We also love that the dress is usually permanently attached to the one-piece swimsuit underneath, so there’s no need to fuss over multiple garments.

When should you start wearing maternity swimwear?

The best time to start wearing maternity swimwear is when your regular bathers no longer fits comfortably. This is usually around 4-6 months into your pregnancy but can vary depending on your size and how quickly your body is changing. Maternity swimwear is designed to provide extra support and comfort, and it’s a great garment for keeping active during a summer pregnancy.

Why you should invest in pregnancy bathers

The main reason to take the plunge and invest in a maternity swimsuit is that it provides extra support and coverage that can be difficult to find in regular versions. It is designed to be comfortable and flattering, so you can feel confident while you enjoy your time in the pool or the beach. Additionally, maternity swimwear is designed to accommodate your changing body shape, making it easier to find a suit that fits you properly. Lastly, when you invest in a quality maternity swimsuit, you can wear it through multiple pregnancies, which can help you save money in the long run.

Can a pregnancy swimsuit still be stylish?

Absolutely! There are loads of bump-friendly swimsuits in Australia, purpose-built for style as much as function. From perfectly positioned side ruching to stunning necklines and gold hardware, contemporary features are much like what you’ll find in regular designer swimmers. So, if you’re worried about the daggy pregnancy gear of the past, fret not mama, today’s maternity swimwear is nothing short of fabulous.
