Our Swim Guide for 2025 Is Here!
Summer 2025 is calling, and it’s bringing bold confidence, cut-out moments, and timeless silhouettes with a twist. Whether you’re dressing for a sun-drenched holiday, a rooftop pool party, or your local beach hangout, this season is all about versatile, standout swimwear.
We’ve made sure you don’t have to choose between style, substance or sustainability. Here’s our top 5 trend picks - all available right now, all made-to-order in the UK from eco-conscious materials.
1. Cut-Outs Are So In
Meet your new obsession: the Tropic Tides Swimsuit.
Thoughtfully designed to sculpt and flatter, this swimsuit is proof that cut-outs can be both daring and supportive. The strategic placement enhances natural curves while the high-waisted bottom visually elongates the torso, making you feel as good as you look.
🌴 Two moods, one suit: The deep black side brings serious elegance. Perfect for a beach club or sunset dinner moment. Flip to the warm brown reverse and suddenly you’re pool-party ready. Add some gold jewellery and you’ve got a whole look.
This is swimwear that works hard and plays harder.
2. Earthy Tones Are In Full Flow
Think grounding, glowing, and effortlessly cool.
This season, rich neutrals are the power move, and our Espresso colourway leads the charge. Deep, luxurious, and flattering on every skin tone, Espresso is available across all That ’Kini styles - from our sculpting one-pieces to cheeky bikinis.
Even newer? Our Marble Drift pattern blends natural tones with a fresh twist — a subtle swirl of earthy elegance that turns heads without trying too hard.
3. The String Bikini: 2025’s Ultimate Essential
Minimal lines. Maximum impact.
This is the year of the string bikini, and our Sea Breeze Top and Side Tide Bottoms bring the classic to new heights. Tie it how you like it, flip it how you need it — each side gives you a different vibe, so it always feels fresh.
✨ Styling tip: Add stacked gold jewellery, beach waves, and your favourite sunnies - and you’re effortlessly that girl.
4. Bold Colours Are Making Waves
Because subtle was never our thing.
Every That ’Kini piece is designed to stand out, whether you’re by the pool or in the sea. Bright, brave and joyfully loud, our bold colour palettes are intentionally chosen to make you feel empowered and alive.
But here’s the twist: most pieces feature a flip-side print, giving you two bold looks in one. Loud on one side, louder on the other — we’re not here to blend in.
5. Florals Are Back (Let’s Be Real - They Never Left)
And we’ve made them bolder than ever.
This season’s must-have florals are vibrant, oversized and completely unique to That ’Kini. You’ll find a custom floral print on the reverse side of every swimsuit.
So when you flip your That ’Kini? You’re not just switching up your look, you’re stepping into a completely new vibe.
🌱 Style That Stands for Something
All our swimwear is made-to-order in the UK from regenerated ECONYL® nylon, which means less waste, and a lighter footprint. Reversible designs = more looks with less impact. That’s always in style.
Founder Picks: My Top 3 Favourite That ’Kini Designs This Summer
Yes, I designed them all. No, I technically shouldn’t pick favourites. But here we are.
OK, so I may be biased… but when you’ve sketched, sampled, and styled every piece yourself, I think you’re allowed to have a few absolute go-tos, right?
Honestly - this is like choosing a favourite child. Every That ’Kini piece has a story behind it and a little piece of me in the design. But if I had to choose (and I’m doing it anyway), here are the three styles I’ve not stopped wearing this summer:
1. The Tropic Tides Swimsuit
She has GOT to be number one. The OG.
The swimsuit that started it all for me - and still one I go back to time and time again. She’s just so versatile. I’ve worn her as a statement piece on a yacht in Italy, and then literally styled her with a sequin skirt and cowboy boots for my trip to Ibiza’s biggest nightclub. Same suit. Completely different vibe.
It’s the shape for me - the cut-outs are carefully thought through to flatter your figure in all the right places. You get that little push up at the bust, the high waist that gives you that hourglass look, and just the right amount of drama without sacrificing support.
Oh - and don’t forget she’s reversible. The black side is so chic and classy, perfect for a beach club moment. Flip to the brown side and you’re ready for a pool party, paired with gold jewellery and a spritz in hand.
2. Anything in the Aqua Bloom Colourway
OK this might be cheating because I’m technically talking about every style here… but can we just take a moment for Aqua Bloom?
I’m OBSESSED. That perfect pop of blue has me in a chokehold this summer. I want to argue that aqua blue is the real it colour of the season - over buttery yellow (I said what I said 👀). It’s fresh, it’s fun, and it literally suits everyone. Every time I wear it, someone asks where it’s from.
Whatever style you go for: string bikini, bandeau, one-piece - Aqua Bloom just hits different.
3. Sunseeker Cheeky Bottoms
OK… I never thought I’d say this, but I’ve been fully converted from thong girl to cheeky bottom girl.
I’ve always leaned toward less coverage, but the Sunseeker Cheeky Bottoms have completely changed the game for me. That little bit of extra coverage? LOVE. Still sexy, still flattering, just with that extra comfort and confidence in the sun. And I know so many of you have been asking for something like this.
The way they sit on the waist is everything. Super flattering, curve-hugging, and they still give that sculpted hourglass effect. Trust me, I didn’t expect to fall for them this hard either.
💬 Honestly… I’m So Proud
On a serious note - I’m so proud of every single piece. Designing these isn’t just about how they look, it’s how they make you feel. Strong, confident, comfortable, and completely yourself.
If you’ve tried any of these styles (or even if you haven’t yet), I’d love to hear your thoughts. Feedback honestly means the world to me - and so much of That ’Kini is shaped by you.
Thanks for being on this journey with me!
