Product development / Technical design portfolio
From first sketch
to final fit.
I am a product development specialist with extensive expertise in costings and technical design. I possess the technical ability to translate a designer's sketch into a garment that a factory can efficiently produce and ship. My experience covers wovens, full fashion knits, leather, swimwear, denim, and cut-and-sew knits for a wide range of clients, from contemporary runway labels to mass-market programs.
I take full responsibility for the technical lifecycle of a product, including:
- Writing comprehensive specs and grading sizes.
- Managing all fit rounds.
- Ensuring every quarter-inch is held to strict tolerance.

Selected work
Five garments, documented the way they were actually made.
Not lookbook shots, but the working documents: annotated sketches, graded specs, fit audits and bills of materials, made browsable instead of buried in PDFs.

Levie S/L Mini Dress426-1100-K
An accordion-compact knit engineered through five fit rounds: 3D fins, ottoman transfer stitches and a sunburst skirt taken from illustration to approved TOP.

Process
A garment isn’t designed once. It’s designed five times.
Every case study on this site moves through the same gauntlet. The craft of technical design is holding the original intent steady while the garment passes through it.
01
Development
Translate the sketch into an engineering brief: stitches, seams, yarns, target specs and reference styles a factory can act on.
02
Proto
First physical sample. Silhouette decisions get made here: what the drawing promised versus what the fabric will actually do.
03
SMS / Fit
Salesman samples and fit rounds on a live model. Every deviation is measured against tolerance and dispositioned in writing.
04
PPS
Pre-production sample in real fabric and wash. The last chance to correct before money is cut in bulk.
05
TOP
Top of production. Audit the first units off the line, bring strays back to spec, approve to ship.
