Give each style an unambiguous identity
Assign a style code and revision date. Include front and back drawings, detail views and a short intended-use description. Identify the people who will wear it, the tasks they perform and any garments or equipment worn with it. Reference photos help explain the direction, but mark the exact details you want to retain or change.
Specify measurements and how to take them
Include a base-size measurement chart with labeled points of measure. State whether a dimension is measured flat or around the body, and show where the tape starts and ends. Provide tolerances and the intended size range. A waist measurement without a measurement method can mean different things on an elastic-waist garment; explain relaxed and extended measurements separately when needed.
Build a material and trim list
List fabric composition, weight or a physical reference, color standards, lining, thread, buttons, zippers, drawcords and labels. Identify requirements that are fixed and those open to sourcing suggestions. Include the care routine and any required performance tests. Avoid using a broad phrase such as durable fabric as the only acceptance criterion.
Show construction and branding details
Add close-up diagrams for pocket openings, reinforcement, vents, closures and seam placements. Supply vector artwork, dimensions and placement distances for logos. For easy-dressing apparel, describe the opening sequence and closure access. For uniforms, show where staff names, department colors and identification should appear.
Define the order and the approval gate
Add estimated quantities, color and size ratios, packing instructions and the target delivery date. Keep delivery timing separate from sample approval timing. Ask for unresolved items to be flagged before sampling, then record the final changes in the tech pack. The approved sample and current documents should describe the same garment.
