June 1, 2023 . 4 mins read
  • Introduction

    The tech pack is a cornerstone of the fashion design process. But where do you start? What essential information do you need? And what pitfalls should you avoid? 

    This guide will walk you through everything you need to know about creating and editing fashion tech packs. 

  • What is a fashion tech pack?

    A fashion tech pack (or technical package) is a comprehensive document provided by brands or designers to factories. It details how to make, construct, and assemble garments or fashion products, acting as a blueprint to ensure proper garment production. 

    Typically used for large-scale production, tech packs include technical drawings, measurements, grading rules, colorways, bill of materials, construction details, costing sheets, and reference images. For smaller production lines, a spec sheet might suffice. 

    In short, a tech pack fashion contains all necessary information for efficient and accurate garment production at the factory level.  

     

  • What Does a Fashion Tech Pack Include?

    To the untrained eye, the contents of a tech pack can seem like an indecipherable collection of technical jargon. But if you know what you’re looking at and how to use it, it’s straightforward!  

    Here are the key components that should be included in your fashion tech pack: 

    • Product Summary: This should be brief but clear, mentioning the article name, code, short description, product type (e.g., jacket, shirt, top), color, gender, date of creation, last modification date, season, supplier/country of origin, and retail price. 
    • Technical Flats: Also called technical drawings or fashion illustrations, they show how a garment would look when laid flat on a flat surface (hence the name). You must include technical sketches of how the products look from all angles—front, back, side and inside. 
    • Measurements/Grading Specs: Measurement sheet outlines all measurements across all sizes for each garment design to help ensure proper sizing later during production. It should also include tolerances for the respective sizes. 
    • Color Definition: This defines what colors the garment is available in. While colorways will show how these colors look when combined or with other fabrics or materials. You might want to provide a few different options here for your manufacturer to choose from. 
    • Bill of Materials (BoM): The BoM shows all the fabrics and trims that go into a particular piece. You could also include information about hardware for zippers and buttons under this heading as well. This document is particularly important as it’s referenced by both parties for costing purposes as well. 
    • Construction Details: construction details will tell the manufacturing team how each part of the garment should be put together—from stitch types on seams to placement of pockets to closures like buttons and zippers. 
    • Care Information: This outlines how end customers can clean/maintain each garment once they purchase it, so apparel products stay in good shape over time. These instructions may not necessarily need to come from you—you can always ask your manufacturer what they would recommend here instead. 
    • Cost Sheet: A garment cost sheet is a detailed list of the costs associated with designing, manufacturing and shipping a garment. It includes the costs of fabric, trims, and labor (with respective quantities) for each garment. 
    • Comments & Feedback: This is where the product development team can review the sample and add comments/feedback for any changes they expect from the manufacturer. This will help them make sure they’re on track with your vision for the product.
