A good fitting wetsuit makes a huge difference to staying warm in open water. But what should you wear underneath? From swim shorts and sports bra style bikini tops, to seam-free swimsuits, you need your swimwear to be soft and comfortable like a second skin – and freedom of movement is critical.
In many ways, a two-piece is better than a one underneath your wetsuit. This is for a number of reasons. First of all, a sports bra style bikini top will give you support while you surf, paddle or swim. Secondly, a bikini top and bottoms are less likely to move around under your wetsuit. But most of all, a two-piece is easier to get on and off when you change.
On the other hand, a swimsuit can give you more protection against chafing than a bikini, but with one caveat – the seams must be super-soft. Picking a swimsuit that fits really well gives you an extra layer of protection between your wetsuit and skin.
Whatever you choose to wear underneath your wetsuit, the fit is key. Your wetsuit must be tight fitting to protect you from cold water. Wetsuits work by trapping a thin layer of water between the neoprene and your skin. That water then warms up to your body temperature, and that’s what keeps you warmer. If your wetsuit is too small, it’ll restrict your movement. But if it’s too big, the cold water will gush through the wetsuit actually making you colder than if you weren’t wearing one at all.
So, if your wetsuit is nice and tight, you’ll need your swimwear to fit like a second skin. That means thinking about:
All our swimwear is made from super-soft fabric with a four-way stretch so that it fits snugly on different shaped bodies. We use a unique sizing system too, meaning you can pick your dress size and your bust size to get the perfect fit and support. And our swimwear is cut for freedom of movement.
We picked out our top three pieces for wearing under a wetsuit.
The Swimbra with Swim Shorts or High Waisters
The soft and virtually seamless Swimbra is our favourite bikini top to wear under a wetsuit. It pulls on over your head, giving you great support. Zipping up with a discreet, flat zip on your spine, there’s nothing to dig in or rub against your skin. The muscle back and low-cut arm holes also gives you plenty of freedom for movement without chafing. Pair with the High Waisted bikini bottoms or Swim Shorts for extra protection on your legs.
Best for: Movement and flexibility – and easy changing.
Top tip: We love The Swim Shorts for surfing because there’s no chance of a wedgie!
The X-Back Swimsuit
Our softest swimsuit, The X-Back has no leg seam around the bum and the double layer of fabric means that it has no inner seams either. The cross-shaped back not only looks fab, but it’s also designed with freedom of movement in mind – no straps slipping off your shoulders, and plenty of room for chafe-free paddling. Plus, it comes in a range of brilliant colours – it’s only a shame when it’s hidden under a wetsuit.
Best for:Seam-free comfort and an extra layer of warmth.
Top tip:This is our favourite swimsuit to wear under open water swimming wetsuits.
The Long Sleeve
When it’s really cold, you need every layer of warmth you can get. The Long-Sleeve Swimsuit is already a favourite among surfers and paddlers, and in the winter months it just gives that added level of protection. The fabric on the body is double layer meaning no inner seams to chafe against your skin. And because the sleeves are made from a mesh fabric, they give you extra movement for those paddling arms.
Best for:Extra protection from the cold and a rash-vest style barrier between your skin and neoprene.
Top tip: Giving you sun protection in the summer and extra warmth in the winter, we love The Long Sleeve Swimsuit for year-round fun in the sea.
We've developed our unique Muse Measurement sizing system to offer a comfortable, sleek and sculpting fit, whatever your shape or size.
We know that no two “size 12” bodies are the same, so our sizing is tailored to three different body shapes:
Step One: Pick your usual UK dress size from 8-20.
Step Two: Pick your bust size based on our Muse Measurements system:
|BRA CUP SIZE||AA - B||C - E||F - HH|
So if you typically wear a UK size 14 and wear a 34A bra, you’d order a 14 Hepburn. Likewise if you’re a UK size 10 and wear a 30F bra, you’d order a 10 Hendricks.
All our pieces are designed to offer stretch. However, if you’re in between sizes we recommend sizing up.
If you are very long in the body, we also recommend going up a dress size to offer additional length.
Our Swimbras & Swim Crops are designed to fit snugly so that you feel 100% secure as you move. We have developed a precise Bikini Sizing System to help you identify your correct size.
|BIKINI TOP SIZING||Cup Size|
Band Size (inches)
|26-28||8 Hepburn||8 Monroe||8 Hendricks|
|28-30||10 Hepburn||10 Monroe||10 Hendricks|
|30-32||12 Hepburn||12 Monroe||12 Hendricks|
|34-36||14 Hepburn||14 Monroe||14 Hendricks|
|38-40||16 Hepburn||16 Monroe||16 Hendricks|
|42-44||18 Hepburn||18 Monroe||18 Hendricks|
All our knickers come in standard UK dress sizes from size 8 - 18.
We currently offer all bikinis in sizes 8-18 and all swimsuits in sizes 8-20.
We are very aware that our size range is still relatively limited. We’re a small independent brand, and have focused initially on offering a highly comprehensive and effective set of products to women who wear dress sizes 8-20.
However we are very responsive to demand. If you would like to see more sizes in different types of products please get in touch at firstname.lastname@example.org - we'd love to hear from you.
For example, when we first launched back in June 2017 we tested customer demand for our products in sizes 8-16. So many of you got in touch to say that you were interested in our swimwear but needed larger sizes that within six months we expanded our size range up to UK size 20. We're really listening to you.
