Side by side
Direction
Sunk cost looks backward. Opportunity cost looks forward.
Impact on wardrobe
Sunk cost fills closets with guilt-kept items. Opportunity cost prevents adding more.
Emotional driver
Sunk cost is driven by loss aversion. Opportunity cost is driven by optimization.
Solution
Sunk cost requires accepting the money is gone. Opportunity cost requires evaluating alternatives.
- 01
Sunk cost: keeping a $400 coat you never wear because selling it for $100 feels like losing $300.
- 02
Opportunity cost: choosing a $120 blazer over a dress because it creates 15 outfits vs 3.

Can you mix elements of fashion sunk cost and fashion opportunity cost?
