I have worked on this wardrobe for twenty years, and I understand it a little better each year. Most of the changes I make are subtractions or simplifications.
Instead of making clothes for a range of life moments, I focus on one: everyday life. Instead of jeans and khakis, I choose jeans. Instead of multiple fabrics within a category, I look for the single best one. Focus limits wardrobe sprawl. I trade variety for consistency.
Fit options are the most challenging part of running this business. I keep them because each one is important to someone.
The wardrobe is dependable and permanent. It is an alternative to the constant churn of the clothing industry. You can read my design references.
