From a young age, Dewy was drawn to the world of fashion. Her formal education in fashion design began in Amsterdam and Tilburg, where she enhanced her knowledge and skills through additional coursework focused on garment design and construction. After experiencing a significant life change in 2010, Dewy decided it was time to step out on her own and launch her brand. In 2021, she founded T’ Atelier, which encompasses several business lines including outsourced sewing for small businesses, sewing seminars, and the production and distribution of its own designs throughout the Benelux region. Dewy is committed to sustainability, frequently utilizing deadstock and upcycled clothing in her work.
