About this piece

After trying our glove-like bikini bottoms, nothing else will ever feel quite right. With sculpting support and a double-sided design in vintage polka dot and jet black, the Dorothy Bikini Bottoms balance playful charm with effortless performance. Thoughtfully made to flatter and designed to move with you, they hold more than your shape… they hold the feeling of being completely, quietly confident in your own skin.

Finished with binding at the leg openings to ensure a snug fit that securely holds your cheeks in.

Pair with the Dorothy One-Piece Wrap Top to create a 6-in-1 set that will make you wonder how you ever travelled without.

Some sizes in this style are on Pre-Order. ETA: Early September. Thank you for your patience. 

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.

Reviews

Love the feel of the

"Love the feel of the fabric, the sculpting and smoothing. Once I worked out there was a front and back to the bikini top pieces 🤦‍♀️ I found the fit was perfect! Such a clever design. I haven’t worn a bikini since the 90’s! Standby for a pic of me swanning around Bali being a total Cha Cha diva! 💃🙌 (Can’t work out how to attach a current pic to this review so will email separately)"

— Kate M. (5/5)

The sizing conversion is a

"The sizing conversion is a bit confusing. When you receive your product in a different sizing conversion its also a bit confusing. Makes you wonder if you ordered correctly."

— Tonya M. (4/5)

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'm really struggling, since weight

"I'm really struggling, since weight loss which has vitually left me with no bum, to find swimmer bottoms which don't gape and flap around my bum. I've gone down a size in the Limoncello Reversible Bikini Bottoms and still a little flappy, however due to the high level of adjustment available, I can really pull the bottoms up into a high cut at the back while still maintaining coverage in the front, and they're still comfy. I'm short waisted so I'm folding the excess at the top over. It would be great if there was a ruched style available though for those with my issue, because at 67yo I'd prefer not to have it so high at the back."

— Sandy D. (4/5)

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)

Very firm getting on the

"Very firm getting on the first time but well worth it! Like wearing control briefs but not tight. Very comfortable once on."

— Suzanne C. (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)

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
