Meet Rachel.

As a child, I was mesmerised by the beauty of fabrics in the fabric store.

I could choose the prints, the buttons and the matching yarns. With my mom, this was a thing we often did together. She loved sewing and making mother-daughter clothes. I could choose whatever I wanted, and it felt like a big candy store to me. She sewed and embroidered my dresses. That’s when my love for fashion started, at least subconsciously.

It runs in the family: over 100 years of fashion

One grandmother was a seamstress, and she had a keen eye on all the little details to make sure the garment fitted like a glove. My other grandmother was always knitting and crocheting and making dresses for my baby dolls. We would make them from scraps and leftovers. Reusing waste was pretty normal to me and my grandmother – nothing new. 😉

And then: the dark side of fashion

All I wanted was to work in the Fashion industry – until I faced the dark side of the fashion industry during my study of Fashion Management. It was a single lecture about sweatshops and how children and people were forced to work. This broke my heart. I decided to study these topics more deeply and graduated in 2004 on sustainable fashion, organic cotton and all its benefits in particular. Yet my recommendations about organic cotton to internationally well-known brands didn’t fall on ‘good ground’, so to speak.

I felt in my guts it had to do with the difficulty of change, so I studied change management. I worked in the fashion industry to understand the people, the supply chain, the interconnectedness of individuals and businesses, the culture, the processes and the stumbling blocks towards change.

After my kids reached the age to go to school, I could finally pursue my dream and start my own consultancy RethinkRebels to make a positive change in the fashion industry. My optimism and enthusiasm have always guided me to stay true to myself and be part of the solution, not adding up to the problem. Are you ready to join me on this sustainable ride?

More on Rachel…

I have a BA in Fashion Management, an MA in Social Science, over 20 years of fashion industry experience in various roles such as buying, product management, and sales management in international fashion companies.

With RethinkRebels, we have worked together with 50+ brands out of 10 different countries and have set up sustainable strategies and implemented this pragmatically and collaboratively. These brands include several SER signatories (Social and Economic Council) who have to meet high due diligence reporting standards. And I also teach students of Amsterdam Fashion Institute – designers, marketers and managers. I’m often asked to speak at events (online/offline), panels and discussions.

My goal is to make the fashion industry circular. Because we simply need to do better: for our planet and our children. Together we can achieve this. That is why I share all my knowledge and experience about this with you so that you can understand sustainability better.

I know you want this. Join the rebellious revolution.
