Start with the size guide and the fit notes on each product page. Sheila sizes by your body, not by the label on your last swimsuit. That’s deliberate — measuring against oursize guideis the most reliable way to land your best fit. Our swimsuits are built to be supportive and comfortable. Between two sizes? Size down for a snug, compressive feel. Size up for a relaxed fit with room to move.

Sheila is size-inclusive by design, not as an afterthought. We make every style in AU 6–24 (US 2–20) — roughly XS to 2XL. Every style is fit-tested across a range of body types, with cup-range guidance on the product pages where it's relevant.

Most Sheila one-pieces and tops include a shelf bra with removable foam cups that supports up to DDD/F (US) or E (AU) cup. Styles like the Ash Cropped Rash Guard are best suited to A–D cup. Specific bust support details are noted on each product page. If you're between sizes and have a larger bust, sizing up is generally the right call.

Our sizes are shown in both. The size guide has the full measurements in centimetres and inches, so you can choose by your actual measurements rather than the label.

Most of our one-pieces and tops have a built-in shelf bra with removable foam cups — real support, with the option to adjust or remove the padding. Support level and recommended cup range vary by style, so check the fit notes on each product page. Several styles support up to a DDD/F (US) or E (AU) cup.

No. The fabric is thick, and pieces are fully-lined and built to stay opaque in and out of the water — lighter colours included. It's why we chose a heavier recycled nylon over the thin stuff: you shouldn't have to think about it.

Both. Sheila is built to move — swim, gym, surf, paddle, chase the kids — then keep wearing through the rest of the day. The construction stays put: no riding up, no adjusting, no slipping straps. Swimwear that holds up to real movement, not just standing still on the sand.

Sheila is built around three things most swimwear brands don't do together: UPF 50+ sun protection on every piece (not just select styles), size-inclusive design from AU 6–24 that's fit-tested across body types, and 100% GRS-certified recycled nylon. Every style is also designed to stay put — no riding up, no nip-slips — whether you're swimming laps, surfing or spending the day poolside.

Yes. Sheila is designed to perform in the water, not just look good beside it. The recycled nylon fabric holds its shape and colour through regular pool use. If you swim in chlorine frequently, we recommend Black Sand — chlorine fades vivid colours over time regardless of fabric quality. Rinse your suit in cool water after every swim to extend its life.

Yes. Sheila styles are built to handle more than the beach. Pieces like the Bindi Racerback Top and Ash Cropped Rash Guard are designed for active movement — swimming, gym, surfing, paddleboarding and daily wear. The stay-put construction (no ride-ups or slipping) makes them as practical for training as they are for lounging.

Sheila was founded in Australia in 2023 by Clare Barrins. The brand is designed in Australia, manufactured by trusted specialist swimwear partners in China, and ships from warehouses in Melbourne, Australia and Menlo Park, California.

Yes. Every piece in the range is rated UPF 50+ — the highest sun-protection rating there is — blocking at least 98% of UV. The protection is built into the fabric itself, not a finish that washes out. Styles with more coverage, like our long-sleeve one-pieces and swim tees, simply put more skin under that protection.

UPF stands for Ultraviolet Protection Factor — it's the swimwear equivalent of SPF for sunscreen. UPF 50+ is the highest rating available and means the fabric blocks at least 98% of the sun's UVA and UVB rays. Unlike sunscreen, UPF protection doesn't wear off, wash off or need reapplying. Every Sheila piece is crafted from fabric rated UPF 50+.

A luxuriously thick, supportive recycled nylon, blended with elastane for stretch and recovery. The nylon we use is 100% recycled and GRS (Global Recycling Standard) certified — regenerated from waste like fishing nets, carpets, abandoned textiles and plastic that would otherwise pollute the earth, through a process of sorting, cleaning, regeneration and purification. The fabric is also certified to STANDARD 100 by OEKO-TEX, meaning it's been tested for harmful substances.

• Main fabric: 75% recycled nylon, 25% elastane
• Lining: 80% recycled nylon, 20% elastane

So you can wear it forever: rinse in cool water after every swim, wash in cold water with similar colours, and dry flat in the shade. Avoid rough surfaces and high chlorine levels where you can. Detailed care instructions are on each product page.

Our recycled nylon is chosen to hold up to sun, salt and seasons — but chlorine is hard on any swimwear over time.If you’re regularly swimming in chlorine, go for Black Sand. Chlorine fades vivid colours over time — no matter how good the colourfastness or fabric — so darker holds up best in the pool. Salt or fresh water? Any colour’s fair game.Rinse in cool water after every swim, wash cold with like colours, and dry flat in the shade. Skip the wringing, hot washes and rough poolside surfaces, and your Sheila will go the distance.

We're committed to high ethical standards across the business, and we only work with suppliers who share that commitment to sustainability, accountability and transparency. Our swimwear is made from 100% recycled, GRS-certified nylon, certified to STANDARD 100 by OEKO-TEX (see the fabric question above). Our packaging is recycled and recyclable too — see the next question for detail.

Sustainability matters to us, packaging included. Our garment poly bags and mailers are made from 100% recycled, ocean-bound plastic. Our logo stickers are 100% FSC-certified recycled paper, printed with water-based inks, and home-compostable after use. Our paper inserts are printed on sustainably sourced paper.
