The perfect high rise bottom

. I got a small (different suit in photo but used to show my body type), and it fit pretty perfectly. I’m 5’ 5” or 165cm and usually a UK10 and size Small. For US bottoms I’m a 4 typically. I tried a medium (which is the size I was for the one piece) but it was too big in the waist.

Incredible, so flattering on all body shapes & sizes

Love how this suit shapes my body and made me feel confident!

Absolutely amazing! Love the fit and the fabric 😍😍

Perfect two piece cut

Our two piece bikinis are made with a luxurious sustainable buttery soft fabric. 
They are the perfect intersection of sporty and fashionable.  With a comfortable seamless design, both functional and flattering and a tailored feminine design that is suitable for leisure or athletic activities.

Designed for comfort

We’ve designed our swimsuits for comfort right down to the smallest detail. The luxuriously soft fabric, double lined, with innovative cupless support and smooth seams will hold you in and support you, with all your water activities.

Sustainable Swim

We value slow fashion over fast with a focus on sustainable fabrics and ethical production. Crafted from regenerated nylon that is designed to last twice as long as your regular swimsuit. Our swimwear is designed & made in Bali with love, with 10% of each sale donated to those in need through our Giving Back initiative.


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

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.

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.

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.

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

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