Booked those far-flung flights for 2023 already, and well on your way to curating your perfect summer ‘fits? Or are you slowly emerging from your winter den, holiday talk most definitely a pipedream, for now?

Either way, we’ve got two words for you: Bikini fit. Wave goodbye to unwanted underboob, too-tight elastic and drawstring disasters, because this season is all about a fresh approach to bikini shopping.

When we buy lingerie, we don’t pick a bra-and-knicker set in one size and hope for the best, do we? So why have we been doing this with our swimwear for so long?! At Boux, we’re changing the game, because we know that buying separates in your ideal (top and bottom) sizes is the undisputed key to beach day boldness - and to feeling the very best kind of holiday glow.

So read on, poolside princesses, and discover your best fitting bikini ever…


It’s simple - your bikini top should be as beautifully snug as your favourite bra. All of our underwired bikini tops can be found in bra sizes so finding the perfect fit is easy. The rest of our bikini styles can be found in dress sizes, so try a couple of sizes to get the perfect fit, like you might with a bralette

Remind yourself how to choose the right bra size for a start. Once you’re armed with this knowledge, there’ll be nothing stopping you. Hiding behind that trusty sarong or cover up? A thing of the past. Unless, of course, it’s a playful piece from our latest beachwear collection!

Ask yourself what you need most from this year’s swimwear picks - is it something a little different to usual? Do you need firm support? Or a look that will feel fun and sexy from daytime pool party, right through to sunset sangrias? We’ve plenty of bikinis that fit just like bras. Grab before they’re gone!

Bigger-busted beauties will be delighted to find that at last, there IS a halter style bikini top out there for you. The Ibiza halterneck bikini top features our favourite neckline, with super supportive underwiring and up-to-G-cup availability that means everyone can enjoy this fun style. You’ve just one huge decision to make here; a feisty fuschia or a confident cobalt blue hue this season?

In need of a boost? The Cyprus double boost bikini truly lives up to its name; with a plunge cup, plenty of additional padding and a genuine Bond Girl vibe, it’s the sultry black bikini staple you didn’t know you’d been looking for.

Fundamentally, you need a bikini style and fit that makes you feel empowered, just a little audacious and most importantly - unapologetically, authentically you. If the style, colour and price is right for you, simply follow this 3-point checklist and you’ll feel nothing short of unstoppable.

- Cup coverage - decent, smooth coverage is what you’re looking for. Bikini top cutting into your breasts? Test a size up

- Snug straps - but fitted doesn’t mean skintight. Those red indents on your shoulders at the end of your beach day? A sign to rethink your bikini top size, pronto

- Let’s band together - your bikini top’s band should clasp / tie together with ease, and without that irritating ride-up feeling


Sun-worshipping goddesses and sea swimmers unite, because no matter your most cherished holiday activity, we’ve got you (and your bottom) well and truly covered. Or not, depending on your preference!

Bikini bottoms should skim, smooth and accentuate our favourite bottom-half features. Love to highlight your hourglass shape? High-waisted is the way to go. A self-crowned queen of squats and loving your work? Show it off with a thong-style bikini bottom…we dare you. 

The Ibiza eyelet bikini thong is the ultimate in showing off that booty work - gold ring detailing and adjustable ruching make it ultra on-trend. Match with the Ibiza eyelet bikini top for a look that’s casual yet glam (hello, scarlet red) and you’re set to wow the White Isle all summer long!

High-waisted top of your agenda? Elongate those legs with the Cyprus ring side bikini briefs. When trying for size, ensure they sit along the natural curve of your waist - and why not mix and match with your fave bikini tops too?

At Boux we’re big fans of the tie-side bikini brief. Why? Adjustability! Switch up your coverage and snugness for both your tanning session and those pool lengths (read; float) with the Morocco floral trial bikini set. A gorgeous floral pattern just screams ‘summer is here’ and the triangle top is feminine, cute and will look amazing under a floaty beach cover-up - bohemian beauties, you’ll rock this one.

So how do I know if the fit is right?

We hear you. But there’s no need to overcomplicate things. Your bikini bottoms should neither ride up nor leave any imprint on that sunkissed skin. Found a pair that look the part, feel amazing and you can wear all day long?
Then grab your passport, secure that airport lift and go slay, sister.
