Our guide to swimwear
...that actually fits!
Swimwear isn’t just for the Summer season, we have hundreds of cup-sized swimwear options to choose from online and in our shops all year round! Whether you’re searching for a one-piece swimsuit, tankini, or bikini , we’re here to help you find a style to suit and support you to feel fearless in your swimwear.
Dive into our swimwear sizing and fitting guide and discover the joy of finding fit for you swimwear that actually fits D cups and up!
1:How should swimwear cups sit?
When your swimwear fits well, your boobs should be fully enclosed in the cups – there should be a smooth line, with no ridge or bulging, where the top and the side of the cups end. If you’re bulging out of your cups or there is wrinkling, it’s likely you need a different cup size.
2:How should your swimwear fit at the back?
Your back band should be firm (but comfortable) and horizontal around the body without any riding up or digging in. Some women prefer to go up a back size for extra comfort when lounging at the pool or the beach. If you decide to do so, make sure to drop your cup-size down by one letter to ensure proper support in the cups.
3:Where should the underwire sit?
The underwires in your swimwear should sit flat on your ribcage (not your boob!) all the way round to your armpits. The wires between your boobs should lie flat against your chest without digging in, rubbing or poking out – just like your bra!
What bikini size should I go for?
You might be thinking bikini’s and bras are very similar and you’d be right! Our bikini tops are specifically designed to keep you feeling supported, just like a bra would. If you’ve had a bra fitting and know your size – this is a great starting point when choosing a cup-sized bikini.
All of our bikini tops are cup-sized and sold separately to our bottoms so that it's super easy for you to wear the styles you love in the right fit to keep you feeling confident and supported.
What size swimsuit should I buy?
As our boobs and bodies are wonderfully unique (and we’re all so much more than a measurement), it might be a little bit of trial and error to find the swimsuit size that is the best fit for you. It’s a great idea to start with your bra size and go from there until you find a fit you love – remember, our team of knowledgeable fitters are always on hand over the phone, via virtual fittings, and email with fitting and style advice.
I prefer to cover my tummy, what options do I have?
If you love the coverage of a one-piece swimsuit, but prefer the ease of a two-piece, a cup-sized tankini could be the option for you! They are a great choice if you like to choose your level of coverage as they can be adjusted at the tummy to find the fit that empowers you to feel the most confident.
High waist briefs are another great option for a little extra coverage as they come up higher at the tummy than any of our other bikini bottoms. Lots of our bikini styles have matching high waisted options, or you can style our Mix & Match High Waist Briefs with our supportive bikini and tankini tops, so you can create a look that feels stylish as well as secure.
What options are there for swimwear bottoms?
All our cup-sized bikini and tankini options come with separate bottoms so you can have the freedom to build your supportive swimwear wardrobe depending on the look you’re after. You can mix and match styles together as well as different shapes of bottoms to suit your swimwear style -we love to give you options!
Mixing and matching shapes, colours and patterns gives you the freedom to pair a printed style with a pop of colour on the bottom or embrace the colour block trend by pairing 2 bright colours together – there are so many options to choose from. Check out our mix and match collection for some inspiration!
Looking for a little less coverage? Why not try a classic bikini brief or tie side bottoms? They sit lower on your hips and can be a little bit "cheekier" – perfect for sunbathing! If you prefer a higher coverage option, high-waisted, folded style, or swim short bottoms could be the styles for you to hit the beach or pool feeling super confident!
We stock plain black women's swimwear bottoms 365 days a year so you have lots of options to style with your supportive bikini and tankini tops – all you have to do is choose!
