What is a Tech Pack?

A tech pack is the blueprint of your garment—a detailed document that translates your design vision into actionable steps for manufacturers. It includes all essential specifications like sketches, measurements, materials, colors, trims, and other vital production details to ensure the final product matches your expectations.

Why a Tech Pack is Essential

Clear Communication: Provides precise instructions to manufacturers, minimizing misinterpretation.
Cost Efficiency: Reduces the risk of costly production errors.
Consistency: Guarantees that each piece aligns with the original design, supporting quality and brand consistency by specifying fabrics and performance characteristics.
Professionalism: Reflects seriousness and preparedness, fostering relationships with reputable manufacturers.
Step-by-Step Guide to Building a Tech Pack

Create a Detailed Flat 2D Sketch

A flat sketch (or technical drawing) is essential for clearly illustrating the garment from multiple angles. Include front and back views, and side views if needed, along with all visible design details like seams, pockets, and stitching types.
Develop a Bill of Materials (BOM)

The BOM lists all materials required, detailing specifics for fabrics, linings, trims, and labels. Include precise fabric composition, color, and supplier information, along with detailed descriptions of each trim element, supplier contact information, and quality codes.
Outline Construction Details

Include stitching specifications, seam allowances, and unique construction techniques. Detailed instructions guide the assembly process, ensuring your garment is made accurately.
Create a Measurement Specification (Spec) Sheet

The spec sheet outlines all essential measurements to guarantee the correct fit. List measurements like chest width, sleeve length, and inseam with acceptable tolerance levels to account for production variances. Include a measurement diagram for clarity.
Specify Colourways and Artwork

For garments with multiple colors or prints, specify each color code (e.g., Pantone) and provide high-resolution artwork with precise placement. Include CAD drawings to give manufacturers a clear visual.
Add a Size Grading Chart

Outline the grading rules to ensure a consistent fit across sizes. Include increments for each measurement, adjusting as needed to fit specific sizing standards or regional preferences.
Include Additional Notes and Instructions

Add any other crucial details, including packaging, inspection standards, and shipping instructions, to complete the tech pack.
Tips for Creating a Strong Tech Pack

Be Clear and Detailed: Avoid ambiguity by providing precise information.
Use Visuals: Supplement text with visuals to enhance clarity.
Review and Update: Double-check for accuracy and update the tech pack as needed throughout production.
Conclusion

Creating a detailed tech pack is essential in fashion, as it saves time, reduces costs, and ensures that the final product aligns with your creative vision. A comprehensive tech pack lays the foundation for smooth, efficient production and successful design outcomes.
