Our best-selling and award-winning Signature Swimsuit in classic navy and black is a perfect cossie for your weekly swim and a good quality, trusted holiday staple. You'll love the built-in bust support and the flattering sweetheart neckline. Our Monroe shape is designed to fit C-E cup busts.
Don't forget to go up a dress size in this style as the fit comes up a little small.
I already have this in cobalt, so couldn’t resist treating myself to the Navy version. The most comfortable, well fitting and flattering swimsuit I’ve ever had. Haven’t tried open water swimming yet, but we have a SwimSpa and you have to be very careful what you wear as the pressure from the water flow can lead to things coming uncovered. This swimsuit stays perfectly in place and saves any embarrassing situations! So pleased I found Deakin & Blue ...
This is the best swimsuit I have ever bought and well worth every penny. It is both for swimming and for sun-bathing due to its extremely stylish design. It has had a lot of wear and it still looks like new. It is going to remain a standard item in my swimming wardrobe.
I ordered this swimsuit during lockdown not knowing ... A. If it would fit. B. if it would suit my body type. C. If it would even get from the UK to Australia. Well, it arrived, it fits, I love it and it is now my preferred swimsuit for my daily ocean dips. In fact I even chose to put it on damp from yesterday (winter in Aus) instead of getting an alternative dry swimsuit from the draw.... it is comfortable for freestyle swimming (doesn't pull at the shoulders), it holds everything in, it is warm for cooler water and it looks great. (Personal opinion, no one has actually told me...I am guessing they are all too PC to speak. Haha). Love it.
This smart navy swim suit fits to size. Feels comfortable and has garnered compliments from other woman swimmers.
I love this swimsuit. Whether walking to the pool or strolling to the ocean, doing some laps or lazing in the surf, it holds me in and keeps me together. And, in these times of uncertainty and lockdown restrictions, it has become my favourite outfit for online yoga sessions and workouts with weights. I love the versatility this cossie offers me.
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 email@example.com - 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.
