Honest by Default
No buried disclaimers, no ingredient gymnastics. If it's in our bikini, it's on our website.

Hi, we're Pikini
Designed in Vancouver for beach days everywhere.
Our Mission
To give women back the week of summer they lose every month.
No tampons. No fear of leaks. No missed beach days. Just a bikini that looks like the one you already love, with five engineered layers underneath that nobody can see.

Charlene Bi, Co-Founder, Vancouver BC
A love letter
We're Charlene and Bon, partners in life and in Pikini. It started with Charlene cancelling a girls' trip to Mexico in 2023 because she'd be on day 2. She cried in the airport bathroom about it. That was the moment we realized how absurd it was that an entire generation of women had been quietly editing summer out of their lives for one week a month.
Charlene sketched the first Pikini on the flight home, the visionary, the designer, the one who knew exactly what the bikini she wished existed should look and feel like. Bon, a materials engineer by training, started prototyping the lining the next morning. Five layers, 2.4mm thin, lab-tested and PFAS-free. That became the engineered heart of Pikini.
Eighteen months, 112 prototypes, and 12 brave testers later, what you see today is the version they all said yes to. Charlene runs design and the brand vision. Bon runs materials and marketing. Together, we run Pikini out of a small studio in East Vancouver.
This brand is for the testers, and for everyone who's ever sat on a beach towel pretending to read a book while their friends were in the water.

What We Stand For
No buried disclaimers, no ingredient gymnastics. If it's in our bikini, it's on our website.
We don't test the prototype and call it good. Every drop is verified PFAS-free before it ships.
312 sets per drop. Recycled fabric. Compostable mailers. No warehouses full of dead inventory.
Tested on bodies 24A to 36DD by paid fit models. Not the same one over and over.
How We Got Here
2023
Char cancels a girls' trip to Mexico because of day 2. Starts sketching Pikini on the flight home.
2024
We made and destroyed 112 versions of the gusset before one held up to lab leak tests.
2025
Twelve real testers swam in Pikini for a full summer. Zero leaks reported. Eleven re-ordered.
2026
312 sets across five colorways, brought to life by our partners in Asia, designed with our hearts and minds in Vancouver, BC.
The lining
The part nobody sees is the part we obsess over. Our gusset is 2.4mm of engineered fabric, a recycled outer, a wicking layer, an absorbent core, a leak-lock barrier, and a soft inner.
Every batch is independently lab-tested for PFAS before it ships. No greenwashing, no half-truths, no "we tested the prototype" nonsense.

The Small Team
Co-Founder, Design
The visionary. Designs every cut, print, and trim.
Co-Founder, Materials + Marketing
Materials engineer. Built the five-layer lining and runs the brand voice.

Behind Pikini
Every Pikini set is brought to life by our manufacturing partner in Asia, a small, family-run facility that specializes in technical swimwear. They've spent decades perfecting the cut-and-sew craft, and they're the only team we trusted to handle our five-layer lining without compromise.
The Partnership
We visited the factory floor before signing a single PO. Met the team, watched the stitch, tested the lining ourselves. It took 112 prototypes to get one we'd put our name on.
The Standard
Our partner operates under independently audited labor and safety standards. Fair wages, regulated hours, and a clean facility, these are our non-negotiables.
The Craft
312 sets per drop. Every gusset is sewn and inspected by hand, then every batch is lab-tested for PFAS before it leaves the facility. No shortcuts, no overproduction.
