Flow's founder
Relaunch of Period Swimwear 2026
"Period swimwear is back! We've spent two years perfecting the fit and materials (we've chosen the best Italian fabrics).
Last summer, I tested the function and fit. I'm not usually a water baby, but of course, the samples I had in my suitcase had to pass their big test.
They passed with flying colours. I felt safe, comfortable - and chic. I'm incredibly excited to see you in the swimwear on the beach, by the pool, in gardens".

Frequently asked questions
Please wear your regular size in your swimwear.
If you are between two sizes, we would suggest the smaller one, as the fabric can stretch when wet.
The absorbency of menstrual swimwear is light to moderate.
If you are bleeding heavily, we suggest that you combine it with a cup or a disk.
Our swimwear is designed with a built-in, absorbent layer that captures and encapsulates menstrual blood. This layer is combined with a waterproof yet breathable membrane that prevents you from bleeding through while swimming or sunbathing.
The textiles are light and quick-drying, ensuring that you can move freely and feel dry shortly after being in the water.
1. If you have bled in your menstrual swimwear, rinse them in cold water until it runs clear.
2. Protect your swimwear in a laundry bag and wash your panties with similar colors at 30-40 degrees.
Tip: You can wash with our Allergy Certified special detergent Bloody Clean .
3. Dry them inside out on a clothesline - and you're good to go again.

Jenny – Menstrual swimsuit with elegant design and discreet protection
Jenny is a menstrual swimsuit that combines an elegant, feminine design with discreet absorbent technology. The low back and flattering underbust seams create a timeless silhouette, while the built-in absorbent panel allows you to bathe with greater confidence – even when you're on your period.
The best part is that it's almost invisible. Inside you'll find a discreet absorbent panel with three functional layers, designed to protect against light to moderate bleeding. From the outside, Jenny looks and feels like a regular swimsuit.
How does a menstrual swimsuit work?
Jenny is designed with an integrated absorbent gusset sewn directly into the swimsuit. The three functional layers help provide extra security during menstruation, while the swimsuit maintains its elegant look and lightweight comfort.
The tight fit ensures that the swimsuit stays secure, whether you're swimming, bathing or enjoying a day at the beach.
If you have heavier periods, we recommend combining the swimsuit with a menstrual cup or menstrual disc for extra protection.
Use it throughout the cycle
Jenny is not just made for menstruation.
The swimsuit works just like a regular swimsuit and can be worn all summer long – whether you're on your period or not. This makes it a versatile choice for trips to the beach, the swimming pool, the spa or vacations.
Comfort in and out of the water
Jenny is made from an exclusive Italian swimwear fabric with 4-way stretch that follows the body's movements and provides a comfortable fit. The material dries quickly and holds its shape, so the swimsuit feels comfortable both in the water and on the beach.
The deep back and feminine seams under the bust create an elegant look that makes Jenny a swimsuit you'll want to wear – no matter where you are in your cycle.
