Apparel Tech Pack Guide
This apparel tech pack guide explains how clothing brands organize the technical information a manufacturer needs to develop, quote, sample and produce a garment accurately.
A strong tech pack brings design, measurements, materials, construction, color, artwork and packaging requirements into one organized working document that can evolve through development.
What Is an Apparel Tech Pack?
A tech pack, short for technical package, is the working technical document used to communicate how a garment should be developed and manufactured.
Unlike a fashion illustration, a tech pack is not primarily about presentation. Its job is to communicate measurable and buildable information to pattern makers, sample makers, sourcing teams, production managers and quality-control teams.
The more complete the information, the easier it is for a manufacturer to identify questions before cutting fabric or beginning production.
Designers, developers and manufacturers work from the same specifications.
Materials, construction and decoration information make quoting more meaningful.
Measurements and technical notes reduce decisions left to interpretation.
Approved revisions document how a garment changes through fitting and sampling.
The approved package guides cutting, sewing, decoration, finishing and QC.
8 Core Sections of a Production Tech Pack
Formats vary by brand and product, but most useful apparel technical packages communicate these core categories.
Cover Page & Style Information
The opening page identifies the garment and provides everyone working on the project with one consistent style reference.
A clear product name, style number and revision date prevent different versions of a garment from being confused during development and production.
Brand and product name
Unique style number
Season or collection reference when applicable
Date and revision history
Garment thumbnail or technical flat
Technical Sketches & Flats
Technical flats show the garment without fashion-illustration distortion. Front and back views communicate silhouette, seam lines, pockets, openings, panels and construction features.
A manufacturer must understand the actual garment structure, not only the visual mood of the design.
Front and back views
Side or interior views when needed
Close-ups of special details
Seam, pocket, closure and panel locations
Bill of Materials — BOM
The bill of materials lists the fabrics, trims and components required to build the garment.
The BOM connects the design to physical materials and helps sourcing, costing and production teams identify exactly what must be purchased or developed.
Main and contrast fabrics
Fiber content, construction and GSM where applicable
Zippers, buttons, elastics, drawcords and hardware
Labels, care labels and size tabs
Color references and supplier information when known
Measurement Specifications
Measurement specifications define garment dimensions using consistent Points of Measurement, commonly called POMs.
A drawing communicates shape, but measurements communicate fit. Specification sheets provide measurable targets for sample development and production review.
Base-size measurements
Clearly defined Points of Measurement
Size range where grading is established
Measurement tolerances when applicable
Revision notes after fitting
Construction Details
Construction pages explain how individual garment areas should be assembled and finished.
Two garments can look similar from the outside while using very different seam types, reinforcements, finishing methods and construction sequences.
Seam and stitch requirements
Topstitching and visible stitch placement
Hem, binding and edge finishing
Label placement
Special reinforcement or assembly notes
Colorways & Material Placement
Colorway pages show how each approved color is assigned to individual garment components.
A color name alone may not explain whether rib, body fabric, thread, zipper tape, artwork and trims should match or contrast.
Colorway name
Pantone, TPX/TCX or approved reference where applicable
Body and contrast placement
Trim and thread color instructions
Artwork, Printing & Embroidery Placement
Decoration specifications should define not only the artwork but how large it is, where it goes and how it should be produced.
Saying “logo on chest” is not a production specification. Placement needs to be measurable and repeatable.
Original vector or production artwork
Artwork width and height
Placement measured from garment reference points
Print, embroidery, transfer or production method
Ink, thread or artwork color specifications
Labeling & Packaging Instructions
Packaging requirements tell the finishing team how a completed garment should be prepared after manufacturing.
Finishing and packaging are part of the finished product. Retail labels, SKU information, folding and individual packaging should not be left until the last day of production.
Brand, size and care-label placement
Hangtag and barcode requirements
Folding instructions
Individual packaging requirements
Carton or shipping preparation when required

What a Manufacturer Needs From Your Tech Pack
A tech pack does not need decorative presentation to be useful. It needs accurate, current and understandable information.
Strong Technical Information
- Clear garment drawings
- Base-size measurements
- Material specifications
- Construction details
- Color references
- Artwork files and placement
- Label and packaging requirements
- Current revision date
What If My Tech Pack Is Not Complete?
You can still begin a manufacturing conversation without a perfect technical package.
Reference garments, sketches, photographs, measurement ideas, existing patterns and fabric swatches can help a development team understand where the project stands.
If the garment requires pattern development, fit work or a prototype, those steps should be completed before production specifications are treated as final.
Avoid These Production Communication Mistakes
Using Only Fashion Sketches
Illustrations communicate design direction but may not show garment construction clearly enough for production.
Missing Measurements
Words such as oversized, slim or cropped need measurable specifications before fit can be evaluated consistently.
Low-Resolution Artwork
Preview images may communicate appearance but not provide the production artwork needed for printing or embroidery.
No Revision Control
Old and new versions should be clearly identified so incorrect specifications are not used after a fitting.
Incomplete Color Information
Black, cream or blue may not be enough when exact matching or multiple materials are involved.
Undefined Decoration Placement
Artwork size and measurable placement should be approved rather than left to interpretation in production.

Apparel Tech Pack Questions
What is a tech pack in clothing manufacturing?
A tech pack is a technical document used to communicate garment specifications such as drawings, measurements, materials, construction, colorways, artwork and finishing requirements.
Do I need a tech pack before contacting a clothing manufacturer?
Not always. A complete tech pack is extremely useful, but early projects may begin with sketches, reference garments, photographs, measurements or other development information.
Is a tech pack the same as a pattern?
No. A tech pack communicates specifications and design requirements. A pattern contains the shapes used to cut the actual garment pieces.
Should measurements be updated after fitting?
Yes. When fitting decisions change the garment, the technical specifications should be updated so the current version reflects the approved product.
What artwork format should be included?
The correct file depends on the decoration method, but original vector artwork is commonly preferred for logos, printing, transfers and similar production applications.
Can Euphoric Colors help if my technical package is incomplete?
Yes. Projects requiring pattern making, sample development, fit refinement or production planning can be reviewed to determine which development steps are still required.
