Most women wear underwear that doesn’t fit. Too tight, too loose, or made from synthetic fabrics that irritate the skin.
We wanted to change that.
This course helps you understand how your body, pattern, and fabric interact so you can create underwear that supports your wellbeing, moves with you, and feels like you.
