About this piece

An interplay of periwinkle and salt, inspired by the quiet lustre of pearls and the ever-changing nature of the ocean. A timeless design, made to be discovered in more ways than one.

After wearing these, nothing else will ever feel quite right. An essential that sculpts with precision, the Tide Reversible Bikini Bottoms are secure and supportive, with a reversible colour-block design in salt white and periwinkle blue. Thoughtfully cut to flatter your natural shape, they offer that held-in feeling you’ll want to take with you from sun-drenched coastlines to every escape after.

Pair with the Tide Classic Bikini Top to create a 6-in-1 set that feels like sunshine, softness, and something just for you.

Fabric

Our signature Italian swimwear fabric is made from 85% recycled nylon and 14% spandex, using regenerated fibres from pre- and post-consumer waste, including ocean waste. Luxuriously soft and more flexible than our signature recycled polyester fabric, this nylon blend offers a more relaxed fit while maintaining supportive hold for A to H cups. For a firmer, more sculpted fit, we recommend sizing down.

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
