Passage Summary: Even though some clothes are harder to make, they're getting cheaper because nobody wants them, while popular clothes are getting pricier even if they're easy to produce.

Reasoning: High labor costs usually mean high prices, but current fashion trends are overriding labor costs in determining the market price of clothing materials.

Analysis: This stimulus describes a shift in what drives pricing. Historically, labor (supply-side cost) dictated price, but now fashion (demand-side preference) is the primary driver. We need a generalization that captures this relationship. Look for a principle stating that consumer demand or 'fashionability' can have a greater impact on price than the actual cost of production.
