What I Do
Every engagement is built around one truth: fit is not a technical problem. It's a customer trust problem. I help brands solve it at the root.
01Signature Work
Fit audits, fit block development, size-chart architecture, and grade rules built on real body data rather than assumptions. This is where cross-category fit standards — including extended and plus-size strategy — actually get built.
02
Factory-ready tech packs, clear specs and construction details, and hands-on fit comments through sample evaluation. From first prototype to PP and TOP review, every detail is written to hold up on the production line.
03
End-to-end support from design concept to production-ready handoff — fabric and component direction, sample development, and vendor communication. When fit or construction stalls, I solve it with the factory rather than around it.
04
Department-level guidance for teams carrying more than their process can hold — workflow and capacity review, fit calendars, documentation standards, and sharper WIP reporting. Practical AI integration where it genuinely saves time.

"I don't consult on fit. I consult on what poor fit costs you — and how to stop paying it."
20+ years across fashion design, technical design, and brand operations. I still work hands on — tech packs, fit comments, grade rules — and I help brands build product and sizing systems that hold together across categories.
Based in Southern California.
The Results
In Her Own Words
My approach to fit is grounded in North American body data — built around real North American body measurements. Not assumptions. Proven data.
Work With MeTestimonials
Sofia made an incredible impact on our product quality and significantly reduced our return rates. Her collaborative approach, industry knowledge, and commitment to excellence truly set her apart. Working with her was both professional and deeply rewarding.
Sofia is a true professional — one of the most creative problem-solvers I've worked with. She brings a rare combination of technical precision and genuine care for the end customer. She elevated our team's thinking at every level.
How It Works
We start by identifying what's actually driving fit inconsistency — reviewing size charts, grading, return data, fit evaluations, and current workflows. No assumptions.
A focused working session to align priorities, define fit standards, and identify the changes that will create the biggest impact.
Hands-on execution with your team — refining grading, rebuilding fit standards, training fit teams, and creating documentation factories can follow consistently.
The goal is long-term consistency, not dependency. You leave with fit systems, standards, and processes your team can maintain confidently.
