About Us

Welcome to Peachy Bums
Period Undies & Swimwear Designed for You!

Hey friends, I’m Catherine Bonadio, the founder Peachy Bums, this exciting new brand that’s here to transform your period experience.
I know all too well the ups and downs of growing up and the challenges of finding products that really make you feel comfortable and confident during your period. That’s why I decided to create period undies that check every box—from fit to function, comfort to confidence.

A Little About Me

My family is built around my pretty amazing husband Matt, and our three beautiful daughters. They keep life full of laughter, love, and plenty of challenges (but hey, who doesn’t love a good challenge, right?). Together, we navigate the rollercoaster of raising strong, independent girls.

I’m proud to be leading this brand with them in mind. I wanted to give them a better first period experience than I had.

I bring over 18 years of experience in Product Development & Business Management, having worked with some of Australia’s most iconic brands, including Bonds, Holeproof, Jockey, Tontine, and Dunlop Pillow. This background has allowed me to hone my expertise in creating quality products and now I’m bringing that knowledge to period undies that I know will change your life.

The Journey To Design & Develop The Perfect Period Undies

Like so many women, I struggled to find period undies that were both functional and comfortable—products that didn’t feel bulky, didn’t ride up, and actually stretched over my peachy bum.

Our undies are designed to stretch over everyone's peachy bum, fit comfortably all day long, and give you the confidence to get on with your day without a second thought. Whether you’re at work, at school, out with friends, at the gym, or playing your fav sport, these undies have got you covered.

Our Mission Is Confidence At Every Stage

I believe every girl, teen, and woman deserves to feel confident, comfortable, and empowered during her period—starting from the very first one. That’s why I’ve developed a range of period undies that are:

  • Super comfortable, soft and breathable to keep you feeling fresh
  • Stretchy and snug in all the right places for a perfect fit
  • Leak-proof, providing reliable protection so you can move through your day worry-free 
  • Stylish, because who says you can’t feel cute while on your period?
  • Eco-Friendly, a sustainable alternative to disposable pads or tampons that fill up landfill. 
  • Inclusive, available in a range of sizes to suit ever body. 

Our goal is to create a product range that takes the stress out of your period, so you can focus on what matters most. Whether you’re just starting your period journey or you’ve been using period products for years, these undies will make it easier.

Tested By Real Women, For Real Women

Our undies have been tried and tested by teens and women of all shapes, sizes and ages. These women have provided invaluable feedback on everything from the look and feel, to the functionality and comfort. We listened to you—and now, we’re proud to offer the best period undies out there.
