    Grading (Size Scaling): The base pattern creation service includes the delivery of the size scale (grading) for up to 6 sizes (e.g., XS, S, M, L, XL, XXL) at no additional cost.

    paper FASHION ILLUSTRATION & TECHNICAL DRAWING

    This gallery presents the foundation of all good design. The examples demonstrate how I translate creative ideas into clear technical instructions, covering womenswear, menswear, bags, and shoes. You will see:
    Sketches and Illustrations: Artistic and conceptual drawings focused on capturing the ‘mood’, proportion, and drape of the garment on the body. These are essential for design approval and collection planning.
    Technical Drawings (Flats): Clean, precise, flat views (front, back, and details) that communicate exactly where every seam, cut, pocket, or trim should be placed.
