TikTok has become one of the biggest influences on modern swimwear trends. From beach transition videos and holiday outfit inspiration to "Get Ready With Me" clips and European summer content, the platform has changed how women discover and style bikinis.
The best part? Many of the biggest TikTok bikini trends aren't built around fast fashion. Instead, creators are choosing timeless bikini styles they can wear season after season while creating content that looks effortless on camera.
If you're looking for inspiration for your next beach day, holiday or summer photoshoot, these are the TikTok bikini trends dominating feeds right now.
1. Bright Colour Bikini Trends
Bold colour has made a huge comeback.
Bright bikinis photograph beautifully in natural light and create contrast against white sand, turquoise water and golden sunsets, making them one of the easiest ways to stand out on TikTok.
Popular colours include:
- Citron
- Peach
- Pink
- Bright Blue
- Red
If you love vibrant swimwear, explore the Brooklyn Collection, where bold colours meet timeless Australian styling.
Style Tip
Pair colourful bikinis with:
- Gold jewellery
- Oversized sunglasses
- Neutral linen shirts
- Natural beach makeup
2. Minimalist Black Bikinis
While bright colours attract attention, black bikinis never disappear from TikTok.
Minimal swimwear works because it looks elegant in every location:
- Beach clubs
- Resorts
- Yachts
- Coastal holidays
- Poolside cafés
A simple black bikini creates a timeless aesthetic that rarely goes out of style.
Our Penelope Collection offers a modern take on this classic look.
3. Triangle Bikini Tops
Triangle bikini tops continue to dominate social media.
Creators love them because they:
- Create minimal tan lines
- Adjust easily
- Flatter many body shapes
- Pair with almost any bikini bottom
Triangle bikinis remain one of Australia's most popular swimwear styles for both holidays and everyday beach wear.
Explore our range of Triangle Bikini Collection to recreate this look.
4. Matching Bikini Sets
Matching swimwear has become increasingly popular across TikTok.
Rather than mixing random colours, many creators now choose coordinated bikini sets that create a polished, premium appearance.
Matching sets also simplify holiday packing while making outfit planning much easier.
Browse our Bikini Sets Australia collection to find matching tops and bottoms designed to work together.
5. European Summer Style
One of TikTok's biggest trends has been the "European Summer" aesthetic.
Think:
- Linen shirts
- Woven beach bags
- Oversized hats
- Natural makeup
- Relaxed coastal styling
The bikini becomes part of a complete holiday outfit rather than simply swimwear.
Our collections are designed to transition naturally from the beach to lunch or sunset drinks.
6. The Coastal Clean Girl Look
The "Clean Girl" trend continues to influence swimwear styling.
This look focuses on:
- Neutral colours
- Simple accessories
- Healthy skin
- Effortless confidence
Rather than chasing flashy trends, the Coastal Clean Girl style embraces timeless pieces that photograph beautifully year after year.
The Calliope Collection perfectly suits this relaxed Australian aesthetic.
7. High-Cut Bikini Bottoms
High-cut bikini bottoms remain one of TikTok's favourite silhouettes.
They're popular because they can:
- Elongate the appearance of the legs
- Create clean lines
- Pair with many different bikini tops
- Suit a wide range of body shapes
Many creators combine high-cut bottoms with classic triangle tops for a timeless beach look.
8. Barbiecore Pink Swimwear
Pink swimwear continues to trend.
From soft blush tones through to vibrant hot pink, Barbie-inspired colours remain one of TikTok's favourite summer looks.
Pink bikinis pair beautifully with:
- White beach shirts
- Gold accessories
- Natural raffia bags
- Oversized straw hats
The result is playful without feeling overdone.
Explore the Lyra Collection for pink swimwear inspired by this trend.
9. Mix And Match Swimwear
Rather than buying entirely new wardrobes every season, many TikTok creators now mix different bikini tops and bottoms.
Benefits include:
- Creating multiple outfits
- Extending your swimwear collection
- Expressing personal style
- Getting more value from every bikini
Choosing complementary colours allows you to create fresh combinations without purchasing complete new sets.
10. Timeless Swimwear Over Fast Fashion
Perhaps the biggest trend isn't a colour or cut at all.
More women are investing in quality swimwear they can wear across multiple summers rather than chasing short-lived trends.
Timeless bikinis:
- Photograph better over time
- Remain stylish season after season
- Reduce unnecessary waste
- Become reliable wardrobe favourites
At Dekota Swim, our focus is creating classic Australian swimwear designed to last beyond a single summer.
