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.

Sheila KNOWS summer!

"Sheila in one word: Perfection. This is swimwear that *actually* understands what women want and need. The Grace Mini Shorts naaiiiiled the high-waisted design. I felt supported, not suffocated. I’m obsessed."
GRACE MINI SWIM SHORT
The perfect rash vest does exist!

"I bought the Cate Rash Vest and I love love love it. Why? Excellent fabric, thumb holes with sufficiently long arm length. Yay! Sturdy zip. I will be wearing it for years to come. I reach for it *ALL* the time. "
CATE RASH VEST
MAKES ME FEEL INCREDIBLE

"I get so much more wear out of this piece than I could have hoped for. Perfect for summer hikes to swimming spots, dance classes and styled under an oversized shirt for days running errands. The thing I love most is how incredible I feel when I wear it."
MINA ONE PIECE
My Forever Costume

"*THIS* costume is exactly what I have been looking for. Love the quality and thickness of the fabric. This will be my 'forever' costume. No more board shorts for me!"

Amazing — in and out of the water

MIRANDA LONG SWIM SHORT
Glad I took the plunge!

Women’s Swimwear Designed for Real Life

Sheila makes sustainable women’s swimwear built to move from the water to the rest of your day — early ocean swims, a pilates class, errands, a long lunch. Born in Australia, designed in California. Every piece is cut for a stay-put fit, made from GRS-certified 100% recycled nylon, and rated UPF 50+. Sizing runs AU 6–24 / US 2–20, and shipping is free on every order.

What makes Sheila different

Most swimwear asks you to choose between coverage, support and style. Sheila is designed so you don’t. ...

The fabric is double-lined and supportive, the cuts are made to stay put through real movement, and the silhouettes are polished enough to wear straight off the sand. No nip-slips, no ride-ups, no washed-out colour after a season.

Sustainable swimwear, made from recycled nylon

Sheila is made from GRS-certified 100% recycled nylon, regenerated from discarded materials like fishing nets and ocean plastic. It carries STANDARD 100 by OEKO-TEX certification, so every component is tested for harmful substances. It’s built to last — thick, resilient fabric that holds its shape and colour, so you replace it less often.

UPF 50+ sun protection, built in

Every Sheila piece is crafted from fabric rated UPF 50+, the highest sun-protection rating available, woven into the fabric rather than added as a coating that washes out. That makes it dependable cover for long days outdoors — without an extra layer.

Inclusive sizing: AU 6–24 / US 2–20

Sheila runs from AU 6–24 / US 2–20 and is designed true to size, with secure construction that holds across a wide range of body shapes. Detailed size guides make it easy to find your fit when buying swimwear online, and Try Before You Buy lets you check the fit at home first.

Modest swimwear with real coverage

For more coverage, the range includes high-waisted briefs, longer swim shorts and streamlined one-pieces — refined rather than restrictive, and built to stay in place. Confidence and function, without the constant adjusting.

From swim to studio to street

Sheila is built so you don’t need separate wardrobes for the beach, the gym and everyday life. The same stay-put fit and supportive fabric carry across all three — swimwear you can genuinely live in.
