Hello! I'm the founder of K.ONCEPT, a creative practice specialising in concept development, creative direction and fashion design. I work with founders and brands to develop collections from the ground up, transforming early ideas into considered products with a clear creative foundation. My role often begins before the first garment is designed. Through research, concept development and creative direction, I help define the thinking behind a collection before carrying it through design and technical development. Whether you're launching your first brand or developing a new collection, I can support the entire development process or work alongside your existing team where needed.

Previous experience includes London and New York, with garments designed and developed for artists including Paris Hilton, Nicki Minaj and Gwen Stefani. If you're looking for more than just garment design - someone who can help shape the creative thinking behind a collection as well as bring it to life technically - I’d love to hear about your project.
