What Is a Tech Pack and Why Do I Need One?
A tech pack (also known as technical specifications
or simply specs) is, in essence, a blueprint of your product
that the sewing contractor or factory follows throughout development to
final production. It’s a living document that is updated
frequently during the development process and later becomes a product
history and reference guide for future seasons. The patternmaker
be the factory’s or your own) will use it to make the first
pattern. It’s also a way to document fitting notes, keep track
of fabric and trim usage, and assist with costing.
Flat Sketches / Technical Drawings
A black and white CAD (another name for a flat sketch
or tech drawing) is a detailed drawing the factory or
patternmaker will use to see the details and shape of the garment or
accessory. It is neither a stylized drawing nor a photograph, and
therefore shows a clear view of the stitching lines and other design
details. It can also be colored-up for use on Line Sheets, Mood Boards,
or other documents.
Simply put, the base size pattern (for example, Medium) is adjusted up
(Large and XL) or down (Small and XS) to create the size range. This
occurs after the base size has been fit-approved and any adjustments to
the pattern are finalized.
Establishing Your Brand’s Fit
The notion of “standardized” sizing in the apparel industry
is a misnomer – a person can be a size 8 in one brand, yet a 12 in
another. It’s impossible to fit everybody, so it is important to
make a clear and consistent statement of your brand’s fit. Who
is your customer? What is their body type? It takes an investment
upfront to research and create a fit “block”, but it saves
money on the back end – returns are not only costly, but your
customers won’t be back next season if your products are
