Our story

Sizesset was born from a booklet.
Not a recent one. A set of correspondence course materials from the 1970s, kept by a mother and passed on to her daughter decades later. Inside those pages was a method: structured, progressive, and clear enough to make someone believe they could actually learn to sew, and learn it properly.
That daughter was Célia, and those booklets changed the direction of her life. At the time, she was taking her first steps in sewing, working with magazine patterns stacked on top of each other, trying to figure out which size was hers. The booklets showed her there was a better way. They led her to pursue professional training in patternmaking, and eventually to a career spanning nearly fifteen years in the apparel industry.
Sizesset is what happens when that career meets that memory.
After years of working with fashion brands, designers, and entrepreneurs across the industry, Célia built Sizesset around a single conviction: that good instructions change everything. Not simplified instructions that skip the difficult parts, but complete ones, the kind that treat the person on the other end as capable of learning, doing, and creating something real.
The correspondence school no longer exists. The method lives on.
Sizesset operates across three verticals: Studio, for the professionals and brands that need expert patternmaking support; Draft, for those who want to construct their own patterns with their own measurements; and Patterns, for those who are ready to pick up the fabric and start sewing today.
Whatever brings you here, the work is the same: turning the idea of making clothes into something you can actually do.
