HOW TO CREATE A SIZE CHART

A Practical Guide to Size Charts & Full Body Measurement Charts for Nigerian Ready-to-Wear Brands

Poor fit, inconsistent sizing, fabric waste, and repeated customer complaints are some of the biggest problems Nigerian ready-to-wear brands face — and in most cases, the root cause is incorrect or guessed measurements.

This ebook was created to help fashion brands move from trial-and-error production to structured, quality-controlled systems.
