BUILT WITH INTENTION.
Sustainability wasn't an afterthought. It was the brief.
Every decision runs through the same filter: is this good for the women wearing it, and is it good for the planet? From the fabrics we source, to the trims, to the female owned factory in Bali where every piece is made, to the retailers we choose to work with. It all counts.
We make in small runs on purpose. Less waste, more intention. A product worth keeping.
You don't need a lot of things. You just need a few of the right things.
WHAT WE'RE MADE OF.
Our fabric is sourced from Italy. 78% ECONYL® regenerated nylon and 22% elastane, made from pre and post industrial waste including ghost fishing nets and carpet fluff. The yarns can be infinitely recycled, which is exactly the point.
Every 10,000 tons of ECONYL® eliminates 12,000 pounds of waste and 42,000 tons of CO2 emissions. Those aren't small numbers.
The fabric itself is twice as resistant to chlorine, suntan creams and oils as conventional recycled fabric, with a UV protection of 50. It compresses, sculpts and moves with you without breaking down.
No fossil fuel base materials. No shortcuts.
HOW WE DESIGN.
Every SEPTEMBER suit is sewn by hand at our female owned factory in Bali. No conveyor belts, no shortcuts. Each piece is made consciously, by someone who takes the time to get it right.
We produce only what's needed. That tension between running a business and not overproducing is one we sit with deliberately. It keeps us honest.
Where most brands cut costs on lining, we don't. Every suit and bikini is lined with the same strong regenerated Italian nylon as the outer fabric. That means better shape retention, real support, and a fit that holds up in and out of the water.
The fabric itself outlasts conventional swimwear. That's the whole point.
BUY LESS. BUY BETTER.
The best way to reduce waste is to buy less. And the only way to buy less is to buy better.
Most brands cut corners on lining. We use the same strong regenerated Italian nylon on the inside as the outside. That means real shape retention, genuine support, and a suit that holds up season after season.
One good suit beats three average ones. Every time.
IT GOES ALL THE WAY THROUGH.
Sustainability doesn't stop at the fabric. It runs through every detail.
Our swing tags are made from 100% recycled card. Hygiene liners are biodegradable. Every suit arrives in a reusable organic cotton drawstring bag, packed inside a 100% compostable mailer made from sustainably sourced plants. It breaks down in your compost or green waste. No trace left behind.
We're always looking for ways to do better. If you have ideas, we mean it when we say we want to hear them.
