Babes… TikTok bikini trends have officially taken over our beach bags. The other day at Bondi, I swear I saw three different girls recreating the same bikini transition from that viral sound — you know, the one where they snap their fingers and go from oversized tee to slaying a summer bikini in 0.3 seconds. My iced latte wasn’t even halfway done before another beach babe did the whole slow-mo hair flip thing like she was auditioning for Love Island.
And honestly? I get it.
TikTok bikini trends have become the blueprint for our hot girl summer energy. They’re fun, cheeky, and serve enough main-character vibes to power an entire feed. But while they look effortless on screen, nailing these viral looks IRL takes more than just good lighting — it takes bikinis that actually deliver.
So let’s break down the most iconic TikTok bikini trends right now, how to wear them, and which Dekota Swim pieces are about to make your content blow up.
The Colour Pop Comeback 🎨
It started with @ella.in.bali posting that reel in her neon two piece against a white sand backdrop… and now colour-drenched bikinis are literally everywhere on #BikiniTok.
This trend is all about dopamine dressing — bright, juicy tones that scream “I’m the main event” from a kilometre away. Think electric oranges, zingy citrus, and berry brights.
Bold colour is one of the most fun TikTok bikini trends right now, and it’s not going anywhere — because who doesn’t want to look like pure sunshine on the feed?
Try the Brooklyn Bikini – Citron or Brooklyn Bikini – Peach if you’re ready to glow like a beachside Aperol. These sets don’t just pop on camera — they slay in real life too, especially when you’re sun-kissed and living your best summer fantasy.
Pro tip: Style your colour-pop moment with gold body chains and a slicked bun. Instant “I vacation in Mykonos” energy.

The “Supermodel Off-Duty” Minimalist Look 🖤
There’s something undeniably powerful about that clean, no-fuss aesthetic. @sydneybeachbabe nailed it when she strutted down Coogee in a black two piece bathing suit, sunnies on, zero accessories, just… vibes.
Minimalist bikinis are having a major TikTok bikini trends moment because they let you be the statement. It’s that quiet confidence — the energy of “I didn’t try, I just am.”
If you’re ready to live that fantasy, go for the Penelope Bikini – Black. It’s sleek, it’s sculpting, and it gives that luxe, slow-fashion edge without even trying. The cut is timeless, which means it won’t look out of place in next summer’s TikToks either (iconic behaviour).
Bonus: Black bikinis are flattering under literally every filter. Slay strategically, bestie.
The Micro Top Takeover 👙
Cue the chaos.
Micro triangle tops have taken over TikTok — they’re skimpy, sassy, and built for content. We’re talking minimal coverage, maximum confidence. If you’ve seen @mia.in.noosa doing that slo-mo pool dive in a stringy set, you know the power they hold.
To channel this vibe, go for the Maya Bikini - Aztec. The cut is daring but still supportive enough for real-girl beach days. And the print? She’s loud. She’s confident. She’s about to make your comment section go feral.
Pro styling move: Wear it upside-down (yes, really) for the ultimate TikTok-worthy hack that’s been racking up millions of saves.
Hot tip: All our Maya sets are designed for longevity, not landfill — so while you’re serving looks, you’re also choosing swimwear made to last.
The Barbiecore Fantasy 💖
Pink bikinis have been everywhere since the Barbie movie took over our lives, and TikTok hasn’t calmed down about it. Think bubblegum tones, glossy lip oil, and a flirty “I’m the drama” strut.
Slip into the Lyra Bikini - Pink and tell me you don’t feel like you’ve just stepped off a Malibu dream set. It’s giving hot-girl holiday. It’s giving viral beach reel. It’s giving main character energy.
Pair it with platform slides and a ridiculously oversized hat for the perfect “I’m just casually living my best life” moment.

The Mismatched Moment 🌺
This trend has major that girl energy. TikTok loves the chaotic, playful vibe of mixing different tops and bottoms to create your own custom look.
It’s the easiest way to personalise your swimwear and flex your styling skills. Try the Brooklyn Bikini - Fleurs top with the Brooklyn Bikini - Bleue bottoms — florals meet cobalt for a combo that’ll have your mates begging for the details in the comments.
Also… it’s a sneaky hack to stretch your swim wardrobe without buying a whole new set. (You’re welcome, bestie.)

The TikTok “Clean Girl” Coastal Edit 🌊
Neutral swimwear + dewy skin + salty waves in your hair = peak #CoastalGirl vibes. This is for the babes who want their feed to look like a Kinfolk magazine spread, but still be low-key enough for beach cricket.
The Calliope Bikini – Brown nails that muted minimalist mood. It’s soft, sculpted, and makes you look like you just emerged from a linen-clad seaside shoot. Throw on an oversized white shirt and woven tote, and you’ve just entered your soft-girl era.
This is one of those TikTok bikini trends that actually has staying power — the kind of content that ages well on your grid (no fast-fashion regrets here).
