EXTRA HELP - RASHGUARDS:
Our rashguards are designed with a relaxed, classic tee style fit through the body - as shown on our model. Your usual t-shirt size works best for most customers.
A few things worth noting:
- The fit is relaxed through the torso, more streamlined through the arms and shoulders.
- Fuller or more muscular arms - size up for more room through the sleeves.
- Prefer a firmer fit through the torso than shown - size down.
- Bigger cup size - no need to size up. The design and four way stretch fabric accommodates beautifully, and we have loads of customer feedback confirming this, including from customers up to an 8G cup (wearing our XS).
Our model for this garment, Alice, is a size 10, 181cm tall and wears size S.
On some other styles you'll see Amber, who is a size 6-8, 171cm tall and wears size XS.
ACTIVEWEAR BATHER TOPS:
True to size - go with your normal sports bra size.
A few things worth knowing:
- For a bigger cup size, use your bust measurement against the chart as your primary guide. Our four-way stretch fabric and generous cut accommodate well.
- Not sure? We're happy to exchange or return within 14 days as per our Returns Policy.
Our bathers are modelled by Alice, who is a size 10, 181cm tall and wears our size S.
ACTIVEWEAR BATHER BOTTOMS:
Generally true to size.
A few things worth knowing:
- Slim waist - size down, as the waistband is designed with a fuller waistline in mind.
- Between sizes - size down.
- Four way stretch fabric gives a comfortable, flattering fit without being restrictive.
- Not sure? We're happy to exchange or return within 14 days as per our Returns Policy.
Our bathers are modelled by Alice, who is a size 10, 181cm tall and wears our size S.
LONGLINE SHORTS:
True to size - go for your normal shorts size.
Designed for intentional length and volume, in a classic Bermuda short style. Great for paddling and throwing on after a swim while you dry - but they're designed to swim in them too.
Our bathers are modelled by Alice, who is a size 10, 181cm tall and wears our size S.

F.A.Q.s
WHY OUR GARMENTS ARE WORTH IT
We make sustainable, long lasting UPF50+ fashion. It will cost you less over time, and less per wear, than cheaply made fast fashion.
1. Premium Quality: Our garments are spun from premium quality fabrics. We use high performance, cutting edge technology fabrics, with superior durability and quality compared to competitor fabrics.
Our fabric is engineered to stay looking good for longer, and to last season after season, wear after wear. That means fewer replacements over time - so the actual cost per wear is much lower than fast fashion alternatives that will end up in landfill all too soon.
2. Local ethical production: Our garments are proudly made to the highest standards in Melbourne, Australia by our Ethical Clothing Australia accredited manufacturer. This means high quality control standards apply to all our garments, and it supports local makers who are paid fairly, in safe, clean working conditions. Ethical manufacturing costs more than offshore mass production, but it's a non-negotiable for us. When you buy with us, you're not just buying a garment, you're backing a more ethical fashion industry, local makers and the local economy.
3. Versatlle: Our garments aren't built for throwaway fashion cycles. They're timeless, versatile pieces designed to move with you and not just on the beach - they work whether you're paddling, parenting, or just out and about. Our garments are UPF50+ swimwear that double as UPF50+ activewear and casual wear. This is slow fashion done right: fewer pieces, better quality and a lighter footprint on the planet.
4. Sustainable fashion: Sustainability starts with longevity. When you choose garments that last, you're helping reduce textile waste and overproduction. The "buy less, buy well philosophy" supports a more sustainable future - and gives you something you can feel good about wearing, again and again.
5. Investment in your skin: Our garments are an investment in your skin and long term health. For more about the risks of skin cancer and premature ageing caused by sun exposure over time, see more on our About Us page.
6. Confidence: Our customers consistently tell us our garments are more comfortable and flattering on real women's bodies, compared to standard rashguards. They help you look good and feel great - we want you to feel happy, relaxed and confident on the beach and in the sun.
WHERE ARE OUR GARMENTS MADE?
Our garments are proudly made in Melbourne, where we live and work, by our Ethical Clothing Australia accredited manufacturer.
UPF50+ RATINGS
UPF50+ is the highest rating for sun protection in clothing. It stands for Ultraviolet Protection Factor. A rating of UPF50+ means the fabric blocks at least 98% of harmful UVA and UVB rays.
Our fabric has been independently tested and rated as UPF50+ (Excellent Protection) according to the Australian Government Standard (AS4399:2020) by ARPANSA (the Australian Government Radiation Protection and Nuclear Safety Agency). UPF50+ is the highest level of protection, so you can enjoy the outdoors with confidence knowing you're protected.
In contrast, a standard cotton shirt or tee generally has a UPF rating of around 5. Not solid sun protection, and doesn't even meet the "minimum" protection rating of 15! Think about that next time you see someone throw on a cotton tee at the beach.
In addition, our garments are designed to provide excellent body coverage while still looking flatteringly cute - even our short sleeve tees have sleeves that cover most of the upper arm, our neckline is not gapey (or tight) and we have a lovely flattering torso length for extra coverage.
Unlike sunscreen, UPF clothing doesn't wear off or need reapplying. It's built into the fabric offering consistent protection wherever it covers your skin.
But even with the strongest UPF50+ protection, you are not invincible to UV exposure - seek shade and wear sunscreen on exposed areas. We provide a gorgeous piece of your sun safe armoury.
WHAT SIZE IS RIGHT FOR ME?
We adopt standard Australian sizing. You can choose the best size for you by referring to our Sizing Guide that provides a conversion table to all major country size systems.
The Sizing Guide is conveniently available as a pop up on the page of each product.
Our longline shorts are designed for intentional length and volume, in a classic Bermuda short style, and are true to size - so if your standard shorts size is a size 12, go for our Size Medium. In Australian sizing:
XS = Size 6-8
S = Size 10
M = Size 12
L = Size 14
XL = Size 16.
Our model wears a size S and is an Australian size 10 and 181cm tall.

GLOBAL SUSTAINABILITY AWARD
We are the 2025 Organisation Sustainability Award Winner!
We are proud winners of the global 2025 Organisation Sustainability Award for our responsible rashguards. This award recognises our global leadership in setting new benchmarks in the sustainable fashion industry. From our eco-friendly fabric made from recycled fibres, to our ethical production methods, right down to our packaging - every choice we make is eco-conscious and transparent.
"Their garments aren't just sustainable - they're beautifully made, soft, smooth, and genuinely build to last" - Award founder, Anna Chatburn
Why I Created This Brand
After having a melanoma removed in my thirties, I take sun protection seriously.
But in protecting my skin, I was tired of choosing between sun safety or style. Coverage or confidence. Practical or cool.
Why were we only being offered tight, clingy, triathlon-esque tops - or worse, frumpy cuts with floral prints that felt dated and Mumsy?
I wanted something that looked as cool as my favourite streetwear. Something I could wear from the beach to coffee. On a paddle board or at school pick up. From ocean swims to resort holidays.
So I built it. Now we're redefining what sun protection looks like.
Relaxed. Fun. Elevated. Thoughtfully made.
Premium Fabrics. Australian rated UPF50+. Sustainable production. Australian made.
We don't compromise on quality or style.
I designed our garments for women like me - women who love the sun, but refuse to sacrifice their style to protect themselves.
We choose quality over clutter. We want feel good, versatile pieces.
Thank you for being here and supporting my mission to make sun protection fashion forward and fun.
Warmly,
Carly x
Founder & Designer
