About this piece

Slip into the Riad, a sanctuary of calmness and tranquillity amidst the chaos of everyday life. With its sophisticated white tile print, specifically designed to flatter every form, this bikini bottom is fully reversible and customisable with the elegance of a block midnight navy option on the flip side. 

Wear as a bikini set with the Riad Wrap Top to complete your poolside look. 

Fabric

This bikini bottom has two sides: one is made of Polyester, and the other is made of Nylon. Both of which are Italian-made and recycled. The Nylon side is matte and more flexible than the Polyester side. Bikinis featuring both our signature polyester and nylon fabrics are more flexible than those with only Polyester.

Our signature Italian swimwear fabrics are made using regenerated polyester thread from pre and post-consumer waste. As this piece features shape-controlling properties and high technical performance, please expect it to feel firmer than regular swimwear.

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.

Reviews

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)

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)

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)

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)

These bottoms are so fantastic.

"These bottoms are so fantastic. I LOVE how they really suck everything in without creating bulges and bulk at the edges. They are truly so flattering. The first few times I have worn them, they have been VERY tight to get on, however, after a few wears and swims in them, they are fitting me like a glove! Easier to get on and off and hugging me in all the right places. I am 5'7" and 145lbs for reference and the size 6 US is the perfect size for me on the bottoms. ADORE this print so much!"

— Jaime B. (5/5)

It's good I think. Months

"It's good I think. Months later, I still haven't gotten my full order so it's really hard to review. For a lot of money - I don't think you should wait 4 months for an order but I guess that's where we are. Please ship my dress order in April if you get a chance. Thanks - it's August now, maybe I'll wear it next summer? Also not great for petite's no matter what they say."

— Holly W. (3/5)

After contacting them prior to

"After contacting them prior to making my order, I was authorized to return one of the sizes which I really appreciated. If selling high priced swimwear online, I feel it is unreasonable to only offer store credit."

— sarah Q. (5/5)

The swimsuit was beautiful and

"The swimsuit was beautiful and the material is very high quality. I loved the colour and the versatility. Unfortunately my usual size ran too small (couldn’t get the pants over my thigh to try on) and the top’s arm holes were so small they dug into shoulders. I’ve returned it for the next size up but the return is taking a long time to process. I would recommend sizing up to save yourself the trouble of returning and the lengthy wait confirming the swap."

— Ranika R. (4/5)

Love the print. fit is

"Love the print. fit is good as well. It is a struggle to get on, but once its on its comfy. A little excess of fabric around the waist with the wrap around top. I am sure I will get used to it."

— Maggie T. (4/5)

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
