As a fashion designer, building a portfolio is an essential step to showcase your skills and creativity to potential clients or employers. Your portfolio acts as a fashion resume, demonstrating your best work and design aesthetic. You can include sketches, photographs of your creations (even if they are stitched for dolls!), and designs created using software. This will give a clear idea of your signature style, technical skills, and creative vision to those who are interested in your work. Therefore, it is highly recommended to build a compelling portfolio that truly reflects your talent and passion for fashion.
