Great for surfing

Love that they actually stay on when I’m surfing and I can wear them when I’m on the beach as a normal bikini.

So helpful!

I was not sure about the size for my girlfriend so I messaged the shop for help. They were very responsive and super helpful. Thanks so much team!!!

Very small

I am a US size 8/10 & purchased a medium. The medium is sized for a US 2/4, it is so small and hardly has any backside coverage at all. I would return this but it was only 50.00USD and it's about 40.00USD to mail it back to Australia.

Hey Loni,
We checked your order and you ordered the Midnight colour. As we have listed in every product description and on the size charts, we advise in the Midnight to size up. This is due to the dying process of the fabric to make it so dark, and by doing so, it then does not have as much stretch as the lighter colours. If you go to USPS and return via standard post, not express/registered you will find it is not as expensive. Make sure if you are outside of the 30 day return window to send us an email x

FAQS

Do your bikini tops and rash vests have padding?

All of our swimsuits are double lined and a firm fit so you don't need padding for support.

Which bikini bottom provides the most coverage on your bottom?

The sumatra high waisted bikini bottom provides the most coverage on your bottom. The sumba high rise bikini is the next best for bottom coverage.

What is the fit like for the Bali Bikini & Banyak top?

The Bali Bikini and Banyak bikini top is a smaller cut, designed to be firm so it doesn't move when being active. If you prefer a more relaxed fee, size up and if in between go up two sizes.

Does the Snow white colour go transparent when wet?

All of our snow white seamless bikinis, crop top bikinis and crop rash guards are lined with beige econyl sustainable fabric to prevent them from going transparent when wet.

Which Bikini Bottom provides the most tummy support?

The Sumatra and the Sumba bikini provide the most coverage and support for your tummy.

Are all your bikinis seamless?

Yes all of our bikinis are made with a seamless stitch so they don't dig in to your skin.
