Buying etiquette

The last days in Amsterdam I contemplated a couple of rules I will, from now on, abide by when buying clothes. I will not by clothes for which I will need to buy other clothes. Once, for instance, I bought a dress which could only be worn with a brown belt. And not just any brown belt, a specific color and shape. Naturally this brown belt was never found. I will buy things I will like for a while. Things that don't fall apart. Things that fit. No turqoise. No things I will only wear on special occasions. Those usually never come. No things that could be used as Halloween costumes. No dresses that would look good on a child. No boots with laces as decoration and a functioning zipper on the side.
