Hey babes! Okay, let’s get real — if your sustainable bathing suit can’t take you from Bondi brunch to a Bali sunset in style, is it even worth packing? I tried this look last weekend at Byron, and I swear every girl at the surf club asked me where it was from. Mood: main character energy, obviously.

That’s why we need to talk about the real MVP of summer wardrobe moves: a sustainable bathing suit that actually slays. No flimsy fabrics, no quick-fade colours, no “oops-I-only-wore-this-once” regrets. I’m talking quality-first swimwear you’ll wear beyond the season, pieces made to last, and styles that keep your TikTok-worthy vibes intact from sunrise to sunset.

If you’ve ever struggled with buying swimwear online or wasted hours in a cramped change room only to leave empty-handed, babes, this is your lifesaver. I’m spilling all my tips for sustainable bathing suits, styling hacks, and the must-have pieces from Dekota Swim that will make your holiday look like a whole reel.


Why a Sustainable Bathing Suit is Actually a Flex

So first, let’s define what we mean by a sustainable bathing suit. At Dekota Swim, we’re not perfect — but we’re intentional. Our swimwear might not be made from recycled fabrics just yet, but we prioritise durability, timeless design, and slower production runs, which means fewer replacements, less landfill waste, and a whole lot more confidence on your next holiday.

Honestly, a sustainable bathing suit isn’t just about the environment — it’s about giving you pieces that look expensive and feel luxe without the fast-fashion heartbreak. Think: a curve-hugging bikini two piece that doesn’t sag after one swim, a colour that pops in every Insta post, and straps that actually stay put while you’re chasing waves.


My Top Picks from Dekota Swim (Because I’ve Tried Them All)

Here’s where the magic happens. I’m breaking down my fave sustainable bathing suits that will have you glowing up, slaying, and serving serious summer vibes.

1. Brooklyn Bikini – Citron & Myrtille

Babes, this is the set that literally screams “I woke up like this.” The Brooklyn Bikini – Citron gives me sunshine energy, while Myrtille is perfect for those moody ocean reels. Bonus? Both are timeless cuts that won’t betray you after one season. Pair it with oversized sunnies, a straw tote, and you’re Bondi brunch-ready.

2. Maya Bikini – Fruit Salad & Aztec

If you’ve seen @sophiesummer’s reel in our teal bikini two piece, you know why this set is the moment. Maya Bikini – Fruit Salad is giving bright, playful, vacation energy, while Aztec is perfect for a bold, festival-by-the-beach vibe. These are the sets you’ll wear in every travel reel and never regret.

3. Penelope Bikini – Black

Nothing says effortless chic like a classic black bikini two piece. The Penelope Bikini – Black hugs curves in all the right places, is perfect for a sunset sesh, and honestly, it’s one of those staples you’ll reach for again and again. Pro-tip: style it with a kaftan for day-to-night looks.


How to Style Your Sustainable Bathing Suit Like a Pro

Now babes, you can’t just throw on a bikini and call it a day. Styling matters, and yes, it’s an art. Here’s my guide to making every sustainable bathing suit look like a full-on influencer reel.

  • Accessorise, don’t stress: Oversized hats, layered gold chains, and retro sunnies = instant upgrade.

  • Mix & match vibes: Don’t be afraid to pair your bikini top from one set with bottoms from another. Try Lyra Bikini – Pink top with Scarlett Bikini – Black bottoms for a TikTok-worthy contrast.

  • Beach-to-bar ready: Cover-ups are key. I love a sheer sarong or a mini linen skirt — just toss it over your bikini two piece and you’re cocktail-ready.


What Makes a Sustainable Bathing Suit Better?

I get this question all the time: “Zara, why should I spend extra on a sustainable bathing suit?”

Here’s the tea, babes: sustainable = longevity. A quality-first swimwear piece resists sagging, fading, and uncomfortable fits. It doesn’t need replacing every season, so not only are you saving money in the long run, but you’re also keeping your Instagram feed fresh with pieces you genuinely love.

And honestly? Wearing a bikini that’s designed with intention just feels different. It’s confidence. It’s sass. It’s “I’m owning this summer” energy.
