Our bestselling and award-winning Signature Swimsuit in sleek, classic black is a perfect cossie for your weekly swim and a good quality, trusted holiday staple. You'll love the flattering sweetheart neckline. Sporty swimmer? The low cut under the arms is perfect for active use without chafing. Our Hepburn shape is designed to fit AA-B cup busts.
Don't forget to go up a dress size in this style as the fit comes up a little small.
I love this swim costume, it really is that bit different in style, flattering to the body for a woman with curves and It’s perfect for a serious swimmer as stays in place. I was so fed up with coming out of the water partially exposed as the costume just wouldn’t stay up!
At Deakin and Blue we're reinventing swimwear: developing pieces that are transformational in how they feel, how they move and how they are made.
FEEL BETTERMelanie's body story
"I really love swimming, especially if I’m somewhere like the Mediterranean – getting into that blue water. I love dancing and I like walking. I also enjoy the deep breathing that we do in yoga – it’s often underrated, I think, but can really help how you feel in your body. And a good laugh – I love laughing and find it’s a great way of relaxing."
MOVE BETTERThe Timeless Classic
Designed with you in mind. Our original swimsuit, the Signature, for all you need and more. Here's how:

All our swimwear is made from ECONYL® - a 100% regenerated nylon fibre made from post-consumer waste such as old fishing nets and industrial plastic. So our cossies are ocean friendly, too!
We only work with Oeko-Tex® certified suppliers and environmentally responsible partners who pay fairly, use chemicals safely and minimise waste.

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.
