Fashion flats, also known as tech pack drawings or technical drawings, are 2D illustrations that showcase the design details of a garment or accessory. They are used in the fashion industry to communicate the design and construction details to manufacturers, suppliers, and pattern makers. The purpose of fashion flats is to provide a clear visual representation of the product, including the silhouette, fabric, color, trims, and any other details that are critical to its construction. Fashion flats are typically created using software such as Adobe Illustrator or Photoshop, and they are usually accompanied by detailed specifications, such as measurements, seam allowances, and construction instructions. They are an essential tool for fashion designers, as they allow them to ensure that their designs will be produced accurately and consistently.
