About this piece

Discover Coco, an ultra-high-waist bikini bottom that seamlessly blends timeless style with casual luxury. This simple yet striking contrast creates a contouring effect that flatters shapes of every kind. Embodying a mantra of ”less is more”, the Coco is set to become your new swimwear staple. 

Wear as a set with the Coco Reversible Bikini Wrap Top, or pair with the Black Dahlia Multiway Skirt, Black Long Sleeve Swim Wrap Top, or the Black or White Mesh Sarong for the complete look.

Triple lined with our ultra-firm Italian fabrics for ultimate shape support & sculpting. The additional lining helps to avoid transparency when wet. Please expect this suit to feel very firm at first wear. The nature of our signature fabric is to soften with wear while still retaining shape & support.

We're saying goodbye to this beautiful style and sizes will not be restocked. Secure yours before it's gone forever.

Please choose carefully as this is a FINAL LAST CHANCE item, and we can not offer returns or size exchanges. T&Cs apply.

Fabric

This bikini bottom is made with a recycled, blended Nylon fabric crafted from ocean waste. This nylon blend has a more relaxed fit than our classic recycled polyester bikini tops. If you are after sculpting and shape-wear like qualities in this product we do recommend sizing down.

Size & Fit

Please complete our fit quiz to find your size (located next to size selection above). As this swimsuit features shape-controlling and sculpting properties, please expect it to feel firmer than regular swimwear. Don’t fret as this will soften to your beautiful shape with wear. Read more  here.

Not exactly! While our suits are true to Australian standard sizing, it’s common for women to size down in Baiia suits. The reason for this is because we most commonly recommend sizes based on measurements rather than dress sizes, so many women find their best fit in a different size to what they typically wear in clothing. 

If two or more of your measurements fit within one size, we tend to recommend that one for the perfect fit. If your measurements span three or more sizes, we tend to recommend taking the one in the middle. If you feel you have a particularly short or long torso, you may find a better fit in one size down or up. We suggest emailing us at fitexpert@baiia.com.au prior to purchase if you have any questions or concerns about your correct size.

Our fabrics are resistant to suncream and oils, but we still recommend taking care when wearing sunscreen and/or makeup, as well as taking care to remove marks as soon as possible to prevent staining.

A common ingredient in sunscreen known as avobenzone can contribute to stains, so you may wish to use sunscreens without this component.

For more tips on removing sunscreen and how to avoid staining, we found this article that may help.

HOW TO WEAR

To answer simply: yes, it’s completely normal! But how do I know if what I’m experiencing isn’t normal? We've put together a really detailed blog where we explain what’s to be expected when it comes to trying on your first Baiia swimsuit and tips to getting it on that first time.Read here.

SUSTAINABILITY & CARE

The major difference between the two styles is how many pieces they're composed of.

​The 3-piece Wrapsuit consists of 1 chest piece, 1 body piece and 1 detachable tie; all together they complete a full swimsuit, which you can then reverse, and mix & match with other Wrapsuits to create multiple unique looks. ​

​The 4-piece Bikini consists of the Bikini top made of 2 chest pieces and 1 detachable tie, and the ultra-high waisted Bikini Bottom  - equalling 4 pieces when purchased all together! The Bikini can be worn like a classic Bikini style or made to look like a Wrapsuit, as well as mix & matched with other Bikinis.

SHIPPING & RETURNS POLICY

We offer store credit notes if you wish to return your item for a better fit or because you have simply changed your mind.

Reviews

As expected, I finally got

"As expected, I finally got the right size and it does make me feel very slim. The wrap top doesn't quite boost up the ladies as much as I would like with no passing, but it looks good still. Love the vibrant pattern and the high quality fabric."

— Matty E. (5/5)

I loved the suit but

"I loved the suit but it was too small and needed a simple exchange, now I will be asking for a refund . I sent my order back for a size exchange a month ago and have not received a email confirmation that you even received it. I emailed your company 2 weeks ago for a status update and was told they would be processing my exchange soon but so far no other communication. You seem to be able to send a ton of marketing emails but not updating customers on orders."

— Lora H. (1/5)

The next big thing in swimwear

"Love the high waist for my mature body, and it is very comfortable to wear once I got my size right. Exchanges were hassle free and stressless. Gorgeous style and extremely comfortable. I am in love with this brand and its innovative approach to swimwear for women. the 2-piece options mean it can fit any shape and body image issues just go away."

— Lorin H. (5/5)

Size tip for North American

"Size tip for North American girlies: measure yourself before ordering, and err on the larger size if in doubt. The bottoms do seem (to me) to fit small. Either that, or I’m in denial about my growing perimenopausal posterior ;) Regardless, I’m happy with my purchase, and the versatile looks I can get between this and the wrap top! Four stars reflect my wish for an economical means of trying different sizes before committing to spending so much on a swimsuit."

— Stephanie E. (4/5)

Love it

"I really like how high it goes, you can make it look like a one piece. Once on it’s really comfy but I get what people mean it’s not a stretchy ad a normal swimsuit. I got it on though and once on it feels fine but it was a bit of a battle. Really love the look and feel of this swimsuit. It’s like having a million in one all the ways you can style it!"

— Teagan (5/5)

The best bottoms

"LOVE these bottoms! I ordered a size smaller than normal and so glad I did. They are snug to get on but once on, they do not move, no NOT roll down, and are so comfy!"

— Amanda C. (5/5)

Good quality but I chose

"Good quality but I chose the size badly. The webpage stated that the model had 100cm hips and was a size 8. I couldn't get the 8 over my hips!"

— Michelle R. (3/5)

Stunning print and great fit

"I was unsure about sizing as I'm 12/14. The 14 was sold out so I risked it and I'm so happy i did. Im an hourglass shape so having the firmer fit worked better for my waist. These are smoothing and flattering on."

— caitlin k. (5/5)

dissapointed

"uncomfortably small and tight, yet the leg openings hang open and are not tight on my bottom, so a larger size wouldnt work for me."

— Alisha R. (2/5)

I was nervous about ordering

"I was nervous about ordering the correct size, but with the sizing guide - spot on! Super comfy and very stylish. Can't wait to wear them on my upcoming holiday."

— Catherine B. (5/5)

Q&A

Behind the Design

It was 2016, I had just stepped into womanhood, and with that, was accepting the new shape my body was taking. I was looking for a swimsuit that actually made me look like the woman I knew I was, but was also becoming. Something that accentuated my shape, held me the way I now needed to be held, moved with my body across every season of my life, and came from a place of care for the environment around me. I couldn’t find it. So I decided to make it myself.

I became hooked on creating the dream swimsuit, pieces that didn’t ask you to mould yourself into them, but instead moulded themselves around you. Reversible designs that give you more, unique sizing that honours your shape instead of boxing it, cuts that work whether you’re 29 or 79, pre-baby or post-everything.

Before I knew it, I found myself surrounded by an incredible community of women from everywhere, every size, every stage. They weren’t looking for the “latest trend” or an Instagram moment in a bikini. They just needed swimwear that actually worked:

  • Pieces that held them, supported them, made them feel like themselves
    Reversible cuts that gave them options, not limitations
  • Sizing that didn’t make them feel like they had to change to fit the mould
    Designs that moved through their seasons with them, not against them

That’s what Baiia is built on, women supporting women, and the belief that feeling good in a swimsuit shouldn’t require you to change yourself. That’s the swimsuit’s job.

I’m not here to make aspirational pieces for photoshoots. I’m here to make timeless designs that make you feel held, supported, celebrated, exactly as you are, even on the days you don’t feel like it. Because you deserve swimwear that loves you back.

If you choose to invest in Baiia, please know that I am forever grateful. This community, these women, this belief that we can design our way forward, feeling better in our own skin because we finally realised we don’t have to change.

Thank you for being here. For taking a chance on a brand built simply because one woman wanted to create pieces that held us through the many seasons of womanhood.

From the bottom of my heart,
Amber x
