Using durable clothes for as long as they... endure. Definitely not flash fashion.

Since I live in a poor country, I am allowed to use cotton shirts until too much skin shows (hyperbole, I only allow one small hole) Then, it becomes a rag or a mop 100% of the time.

Having few stains in an worn bought-new shirt is a good indicator of not being rich and still having class.

Eco friendly means unfashionable most of the time. Smaller cars, or even public transport, god forbid.
