Your Body Changes.
Your Swimsuit
Shouldn't Have To.
Most crinkle swimsuits stretch out, lose shape, or leave you adjusting all day. Ours doesn't. We engineered our one-size fabric for real bust support, full coverage, and a fit that adapts to your body – not the other way around. Hit play to see exactly how it works.
One swimsuit. Every stage. Yours to keep.
One suit for every season of life
The everyday
One size that fits AU 6‑16 and cups A‑DD. No guessing, no squeezing.
The bump
Room for a growing bump, without looking like maternity wear.
The baby days
Nursing-friendly straps and stretch that moves with you once the baby comes.
Every age & shape
Supportive fit and medium coverage you can feel confident in, at any age.
Adjustable. Flexible. Bounces back.

Frequently Asked Questions
1. Is it really one size?
Our 'One Size Fits Most' method is suitable for a AU 6-16, depending on desired fit.
The material stretches as your body changes, whether that's weight, age or a baby bump, and returns to your desired shape afterwards.
2. How do I care for my swimsuit?
With the right care, your swimsuit will be your go-to for seasons to come.
Follow these instructions so your suit can continue to feel as good as you do wearing it.
How to avoid any damage or premature wear
- Do not twist or wring, which will overstretch the (already stretchy) fibres of the suit
- Avoid contact with sunscreen, lotions, oils, or bleach. We’d suggest applying suncream, lotions or oils once your suit is on and work your way around it
- Avoid spas or hot tubs
- Do not dry clean, tumble dry, or store when wet.
If you do want to wash your suit, here's how:
- Hand wash in cool, fresh water immediately after use
- A small amount of diluted, mild detergent may be used
- Bunch swimsuit into a ball and squeeze to remove excess water
- Lie in the shade or hang to dry
Don't worry, we'll send these instructions with your swimsuit too.

4. Will it fit my long torso?
It’s likely! It’s seriously flexible - in all directions.
Many people around 6ft tall wear our one-pieces and find the fit to be super comfortable.
5. What about bust support?
Our suits don't include any built-in bust support, as this would limit their special ability to adapt to your changing body.
The super-flexible, seamless fabric adapts to fit your body and will lightly hug your shape in ways a typical swimsuit wouldn't - but this kind of support will come down to personal preference.
Our one-size swimsuit comfortable accommodates cup sizes A–DD
While the suit offers excellent coverage, for extra peace of mind, if you have a large bust or darker areola, we recommend using silicone swimming nipple covers.
6. What is the fabric composition?
Our swimsuits are responsibly handmade in the UK.
The fabric is made of 95% Nylon and 5% Elastane
Pink Sugar Colour: While the suit offers excellent coverage, for extra peace of mind, if you have a large bust or darker areola, we recommend using silicone swimming nipple covers.
