Power isn't always something you have to prove.
Sometimes, it's simply something you wear.
The Zea Adjustable Side Bottoms are designed for the woman who moves through life with quiet confidence. Inspired by Obsidian—the volcanic glass forged through fire—they reflect the strength that's already within you, bringing together bold simplicity and effortless sophistication.
The wider, 6cm side panels create a beautifully balanced silhouette, offering a secure, sculpting fit that feels as good as it looks. Designed to sit comfortably against the body without digging in, the Zea smooths, supports and enhances your natural shape while creating clean, uninterrupted lines that flatter from every angle. The sides can be narrowed as pictured if you prefer a thinner, more sleek bikini bottom.
Individually handmade to order in South Australia, every pair is crafted using premium double-lined recycled swim fabric chosen for its buttery-soft feel, supportive stretch and luxurious finish. Thoughtful construction ensures lasting comfort, allowing you to move confidently whether you're swimming, relaxing by the pool or spending an entire day beneath the sun.
The Zea was never designed to chase trends.
It was designed to become the bikini you reach for, season after season.
Like every piece in the Obsidian collection, the Zea is intentionally produced in limited quantities. Every order is handmade to order, eliminating unnecessary overproduction and reflecting our commitment to conscious craftsmanship. Rather than creating excess inventory, each piece is made especially for you.
Please allow 7–10 business days for your swimwear to be carefully cut, sewn and finished before dispatch. Shipping times are additional.

Made For You
Every Bokinii piece is individually handmade to order in South Australia.
Rather than mass-producing garments that may never be worn, we create each piece only after your order is placed. This considered approach reduces unnecessary waste, prevents excess inventory from ending up in landfill, and allows us to remain true to our commitment to conscious, small-batch craftsmanship.
Please allow 7–10 business days for your swimwear to be carefully cut, sewn and finished before dispatch. Shipping times are additional and will vary depending on your location.
We know waiting requires patience.
We believe creating something worth keeping always does.
