Fashion Pattern Maker & Tech Pack Developer (Reverse Engineer Hoodie)

Hi,

I run a Canadian apparel brand (Flatout Apparel) and I’m looking to reverse engineer one of our best-selling women’s hoodies into a full production-ready tech pack and pattern set.

We already have the finished garment, fabric specifications, and a complete measurement spec sheet across all sizes (XS–2XL).

What we need is an experienced pattern maker who can accurately translate these measurements into pattern files, reverse engineer the garment construction, and build a complete technical package so we can confidently produce this style with multiple manufacturers.

This is a core product for our brand, so accuracy in fit, grading, and construction is extremely important.

Scope of Work

You will be responsible for:

• Reverse engineering a hoodie from a physical sample

• Creating digital pattern files (DXF preferred)

• Translating our measurement spec sheet into accurate patterns

• Developing full grading for sizes XS–2XL

• Building a complete tech pack including:

Measurement specifications

Construction details (stitching, seams, assembly)

Bill of materials (BOM)

Trim details (drawstrings, labels, patches, etc.)

Product Variations

This hoodie shares the same base fit across multiple versions:

• Pullover (fleece)

• Zip-up (fleece)

• Zip-up (terry)

We are also planning a future pullover version in terry fabric.

The goal is to develop a core base pattern and apply appropriate adjustments for each variation.

Product Notes

• Slim/athletic fit with stretch

• Elongated body

• Structured 3-panel hood

• Thumbhole sleeves

• Cotton/spandex blend fabric

We will provide:

• Physical hoodie sample(s)

• Measurement spec sheet

• Fabric references

Deliverables

• Digital pattern files (DXF or AI format)

• Graded size set (XS–2XL)

• Complete tech pack (PDF)

• Clear construction notes suitable for manufacturing

Requirements

• Proven experience in apparel pattern making

• Experience creating production-ready tech packs

• Ability to reverse engineer garments accurately

• Strong understanding of grading and fit

Important

Please include examples of previous tech packs or pattern work you’ve created.

Applicants without relevant experience will not be considered.

Quick Questions (please answer in your application)

Have you reverse engineered a garment from a physical sample before?

What software do you use for pattern making (Gerber, Lectra, CLO3D, etc.)?

Can you provide an example of a tech pack you’ve created?

Looking forward to working with someone experienced — this may lead to ongoing work as we expand our product line.

Thanks,

Jean
