What makes Sheila different from other women’s swimwear brands?

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.

Does Sheila swimwear protect against the sun?

Every Sheila piece is crafted with fabric rated UPF 50+. 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.

What sizes does Sheila offer?

Sheila runs from XS-XXL (AU 6–24 / US 2–20) and is designed true to size. The construction is secure across a wide range of body shapes, and detailed size guides help you find your fit.

Do Sheila swimsuits run true to size?

Yes — Sheila is designed true to size. We recommend taking your usual size and checking the size guide on each product page. Between two sizes? Size down for a snug, compressive feel. Size up for a relaxed fit with room to move.

What is Sheila's sizing like for larger busts?

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.

Is Sheila an Australian brand?

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.

Is Sheila swimwear ethical and sustainable?

Sheila works exclusively with manufacturers who meet high ethical standards. All fabrics are 100% GRS (Global Recycled Standard) certified — meaning the recycled content is verified throughout the supply chain — and OEKO-TEX® STANDARD 100 certified, tested against more than 350 harmful substances. Packaging uses 100% recycled ocean-bound plastic mailers and FSC-certified recycled paper. Sheila is female-owned and founded.

Is Sheila swimwear good for lap swimming or pool training?

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.

Can I wear Sheila swimwear for things other than swimming?

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.

Does Sheila offer modest swimwear with more coverage?

Yes. The range includes high-waisted briefs, longer swim shorts and streamlined one-pieces that offer thoughtful coverage and stay in place. The focus is refined, functional coverage — confident rather than restrictive.

Are Sheila swimsuits see-through when wet?

No. Sheila pieces are fully-lined for opacity and support, so they stay opaque wet or dry and through movement.

Can I buy tops and bottoms separately?

Yes. Tops and bottoms are sold separately so you can mix sizes and styles for the right fit — and this season’s Sundown Stripe print is designed to mix and match with the solid colourways.

Is shipping free, and do you ship to the US?

Shipping is free on every order — no minimum spend. Sheila ships across Australia and the United States.

How do I care for my Sheila swimsuit?

Rinse in cool water after each wear, hand wash gently and lay flat to dry. Avoid wringing, machine drying and prolonged sun exposure to keep the fabric and colour at their best.

What is your return and exchange policy?

We accept change-of-mind returns on anything bought online — just send it back unworn, with tags on, within 14 days. Return shipping is at your cost, and our full Returns Policy has the details.

CATE RASH VEST
MAKES ME FEEL INCREDIBLE
