Annemarie de jong

As a fashion product manager/buyer for over 15 years, I have learned a lot about the need for sustainable strategies and how to develop them. I also found all the accompanying reading material, videos by best practices, and resources very useful. Rachel is a super enthusiastic person, a source of information and inspiration. That enabled me to make the newly learned information my own quite fast. The conclusion is that Rachel has turned me into a  rebel, ready to implement this on the work floor and teach my team how to make a positive impact in the fashion industry together!

RethinkRebels gave me countless examples and tools to shape and realize the challenges and opportunities that come with the transition to a circular fashion system. As a fashion designer and consultant for over 15 years, I can now guide my clients even better regarding their sustainable missions with a clear sustainable strategy. This masterclass gives a tremendous amount of knowledge, energy, and inspiration to apply in practice. I highly recommended it to every fashion professional who believes in a circular fashion system but doesn't know yet where and how to start.

In my current role, I want to focus more on sustainability, make more informed decisions and communicate about this more transparently. My struggle was that I didn’t know where to start, how to implement it, and find the right arguments to really inspire my colleagues and the management. In the Sustainable Strategy masterclass, I learned about the basics of developing a sustainable strategy with the right tools, inspiration from other brands, and guidance by Rachel on how to develop this step by step. This resulted in informed decisions, internal discussions with the teams, and step-by-step improvement of our business and supply chain.
