Designers create initial hand-drawn sketches or use design software to outline the garment look.

Choose fabrics and materials (e.g., buttons, zippers, trims) that fit the design and functional needs.

Pattern makers create patterns based on design sketches, cut fabric, and sew the first sample.

Designers, pattern makers, and technical staff review the samples appearance, comfort, and functionality, then suggest improvements.

Analyze the cost based on the samples material, complexity of construction, and projected production volume to ensure it meets the target price.
