The waistband stretches, so you can move between sizes. If your waist is 80cm, you could wear a M or L depending on whether you want it snug or more relaxed. Between sizes? Size up for room, down for a more fitted feel. Still unsure? Email me — I’ll tell you what I’d go with. All garments allow for a +/- 1cm tolerance.

You Weren't The Problem. The Swimwear Was.
Most brands size for a body that doesn't exist - then make you feel bad when yours doesn't match.
Unity Cove was built the other way around. We started with real bodies - broad shoulders, bigger chests, wider hips, smaller waists, post-top-surgery, trans, masc, non-binary, plus-size, small, tall, short - and made swimwear that fits them.
XS to 6XL. Measured on real people. No catalogue samples.
The fabric is soft, stretchy, forgiving. The cuts are considered. The sizing is genuine.
You're not trying to fit into the swimwear. The swimwear is finally fitting you.

Still Got Questions?
Our swimwear is designed for real bodies - including trans, non-binary, plus size, and post-surgery bodies.
Sizing is based on measurements, not gender. We recommend measuring your underbust (for tops) and waist/hips (for shorts), then using the size chart.
If you’re unsure, email: hello@unitycoveswim.com - I’ll help you choose what I’d go with.
Here’s the quick rule:
Athletic Swim Top → size down for support
Active Swim Shorts → size up for room, down for fitted
T-Shirt Rashie → size up for looser, down for fitted
Still unsure? Email: hello@unitycoveswim.com. I'll tell you what I'd go with.
Reviews consistently say yes - especially when you measure first. The three most common review lines:
- "The size chart was totally accurate."
- "They fit beautifully like the size guide indicated."
- "Fit perfectly - thanks to the handy size chart."
When people get it wrong, it's usually because they skipped measuring and went off their usual size. Spend 30 seconds with a tape measure - you'll nail it. If there are any concerns or you need help, feel free to email: Hello@unitycoveswim.com for assistance.
Yes. The fabric is highly stretchy and adjusts to your bust. We've had customers with F+ cups fit perfectly in small bands. The only measurement that matters for choosing a size is your underbust.
The top is designed for a snug, supportive fit, which means it can take a bit of effort to remove. If you have a shoulder injury or limited mobility, you may find it more challenging to take off and I would NOT recommend you purchase.
If you’re unsure, feel free to email
hello@unitycoveswim.com and I can help you decide if it’s right for you.
Many customers wear our swimwear post-top surgery or mastectomy.
The athletic swim top includes removable padding and can accommodate personal inserts or prosthesis if needed. The fit is designed to feel secure without being restrictive.
Everyone’s preferences and needs are different, so if you’d like guidance, feel free to reach out at hello@unitycoveswim.com
Our sizing runs XS to 6XL and is based on real body measurements, not standardised fashion sizing. We recommend measuring your underbust (for tops) and waist/hips (for shorts), then using the size chart.
The fabric is soft, stretchy, and designed to move with your body - not restrict it.
If you’re unsure, email hello@unitycoveswim.com and I’ll help you choose what I’d go with.

Note: we're a small business, so we can't hold stock aside - send it back quickly so we can get the new size out to you. If your new size is sold out, you'll get a refund or store credit (your pick).
Wrap a soft tape measure around your body right under your chest (where a bra band sits). Keep it snug - not tight, not loose - and level all the way around. Don't suck in. That's your underbust number. Match it to the chart above.
Our charts are based on AU sizing, but the best way to choose your size is by using your measurements (underbust, waist, hips).
Because our fabric is stretchy, you may be able to move between sizes depending on your preferred fit.
If you’re unsure, email hello@unitycoveswim.com with your measurements and I’ll recommend your size.
Yes all products were made to be versatile and multi-use, so you aren't just getting a fit that you wear a few times to the beach every year.
The shorts work as everyday shorts, gym shorts, travel shorts.
The top works as a sports bra and a crop top.
The rashie works as a regular t-shirt, a UPF shirt for hiking, or over any swim top.
They're all quick-dry and chlorine-safe, so you can go from pool → gym → dinner without changing.
