How to Choose Maternity Swimwear in the UK - Buying Guide

Pregnancy comes with so many changes that you may not recognise your own body at times, so the idea of donning swimwear can be daunting - to say the least! Don't worry mama, we've broken down the formula for looking stunning while feeling comfortable.

Decide on Your Preferred Style of Swimwear

The first thing on the list is to think about your preferred style of swimwear, whether that's a bikini, tankini, or a one-piece swimsuit. In this section, we'll go through the pros and cons of each type. You'll be looking bumpalicious at the beach in no time!

One-Piece Swimsuits Provide Ample Coverage and Come In a Variety of Cuts

One-Piece Swimsuits Provide Ample Coverage and Come In a Variety of Cuts

The classic one-piece swimsuit is a great shout when you're pregnant, as it comes in many different cuts and styles. Offering a good deal of bump (and often bust) support, a swimsuit will also give you the most coverage - something that many of us find particularly important during pregnancy.


If swimming is your exercise of choice, there are some well-designed swimsuits that boast both chlorine resistance and tummy support, with shape retention material that stretches to fit your body perfectly. Alternatively, fashionistas may want to choose swimsuits with cut-out detailing or a plunge neck to emphasise their curves in all the right places.


A strapless bandeau-style swimsuit looks stylish and will work during early pregnancy, but it's unlikely to provide enough support later on and you might find yourself feeling self-conscious as your bust size increases. Selecting a one-piece based on your body type and how far along you are will hence ensure that you feel your best while soaking up those rays!

Tankinis are Adjustable and Support You in All the Right Places

If you tend to feel a little restricted in a swimsuit, or you simply like the look of a two-piece, it's worth considering a tankini. This kind of swimwear set typically includes a vest-style top and bottoms, so it covers your tummy but shouldn't feel too tight.


There are many styles of tankini to choose from, including those with a halterneck top, maximum coverage briefs, or easy nursing access for after your baby is born. Plus, this type of swimwear is ideal for both before and after pregnancy, as the top and bottoms are adjustable. Total, comfy support for your bust and tummy!

Bikinis Look Cute With a Bump and Have Built-in Features to Boost Confidence

As within pre-pregnancy life, the bikini is the most "daring" of the three options as it offers the least coverage - and usually the least support too. Some mums-to-be might therefore choose to only opt for a bikini in the first few months. Look for sets with adjustable straps, clasp closures, and bottoms with plenty of coverage to keep you feeling confident in the pool.


If a bikini is your preferred style and you want to wear one right up to your due date, go for one with an elastic bust band and high-waisted bottoms for added tummy support and comfort. However far along you are, we think a two-piece always looks cute with a bump!

Synthetics Are Queen When It Comes to Maternity Swimwear

Unlike other types of clothing, maternity swimwear is made from only a few select choices of synthetic materials: polyester, polyamide, nylon, and elastane (or a blend of a few of these fabrics). 


Polyester is the most commonly used because it's soft yet strong, in addition to being resistant to chlorine and UV rays. If you're feeling eco-conscious, opt for swimwear made with recycled polyester derived from plastic bottles and textile waste - this helps to save water and energy as well as reduce greenhouse gas emissions.


Polyamide and elastane (also known as spandex) provide excellent elasticity for bikinis and swimsuits, which is particularly important in maternity swimwear. In fact, both polyamide and elastane can be found in fabric blends such as nylon, providing the perfect balance of durability and stretch

Extra Features Allow Your Swimwear to Adapt as Your Bump Grows

Extra Features Allow Your Swimwear to Adapt as Your Bump Grows

There are some features that you probably wouldn't consider normally when shopping for swimwear, but that will become very useful as your bump grows. Adjustable straps, tie straps, or hidden clips on shoulder straps allow you to adapt the top half of your swimsuit as your bust gets bigger. These features can also be useful if you continue to wear it after birth and into nursing.


Pieces with a tie front, tie bottoms, or a clasp closure at the back help you to adjust your swimwear when needed and make it easier to get on or take off. Bust and tummy support is crucial in later months so opt for pieces with ruched cups or a ruched tummy area, as these give you room to grow while still providing support.


Lastly, if you plan to wear your new swimsuit or two-piece regularly, look for swimwear with high chlorine resistance technology and shape retention properties for a reliable suit that takes you all the way from bump to baby!
