who we are
ABOUT SEAMLY
Seamly began as one woman’s quest to revolutionize the fashion industry.
Frustrated by ill-fitting rack clothing found in department stores, founder Susan Spencer immersed herself in identifying the source of fashion’s poor-fit problem. A systems analyst by trade, Susan began by doing what she does best: analyzing data. She studied over 150 pattern-making software programs, each yielding poor outcomes. It was there she discovered the root of the industry’s issue: all the pattern-making software programs adopted by the industry were developed based on Victorian-era design measurements. No program offered the ability to tailor measurements to allow designers to efficiently scale their design patterns to meet the fit of today’s population.


The deeper Susan dug into the industry, the more impassioned she became to change it.
This passion led to the development of Seamly 2D: an open-source fashion design program that allows fashion design agencies of all sizes across the globe to profitably create their design patterns quickly and easily. To date, over 30,000 designers in over 35 different countries have transformed the way they do business as a result of this groundbreaking technology.
