Frequently Asked Questions

Does your swimwear provide sun protection?

Yes! Our swimwear is made from 82% Polyester and 18% Lycra Spandex, both of which naturally have a high UPF (Ultraviolet Protection Factor) rating. This means they can block up to 98% of harmful UV rays, helping protect your skin from sunburn and damage.

Our Daisy Top is officially UV-certified, providing verified sun protection for added peace of mind. While the rest of our fabrics have not yet been officially UV-certified, this is something we’re working on.

What does the inner bra of the Swim Shirt look like? 

Our built-in bra is wire-free and designed like a sports bra with strong elastic for comfortable support - especially for larger bust sizes. We've also upgraded our elastic for even better support in our latest collection.

Do your swim tops have built-in bra cups?

Yes! All our swim tops include removable bra cups so you can adjust the fit to your preference.

I’ve had a mastectomy. Will your swimwear work for me?

Absolutely! Our co-founder, Velvet, is a breast cancer survivor who has had a double mastectomy, so comfort and flexibility were a top priority in our design. Our swim tops have removable bra cups, allowing you to customize them with or without inserts.

Will the colour fade in chlorine?

No! Our swimwear is made with high-quality, chlorine-resistant fabric that maintains its colour and shape - even after hundreds of swims.

How should I care for my swimwear?

To keep your swimwear in top shape:

• Rinse with cool water after each use
• Hand wash with mild soap
• Lay flat to dry (avoid direct sun exposure when drying)
• Do not bleach, iron, or tumble dry

Do your swimsuits have tummy control?

While we don’t use compression fabrics, our designs offer great coverage and a flattering fit to help you feel confident.

Can I wear your swimsuits for activities like water aerobics or paddleboarding?

Absolutely! Our swimwear is designed for movement, making it great for swimming, water sports, and active beach days.

Why We Chose Our Fabric
