best-dressed syndrome
The obsession to always be perfectly dressed for the occasion. This syndrome usually afflicts recipients of the "best-dressed" award in high school yearbooks. People with this problem will feel the need to change clothes multiple times in a day, and even design an elaborate outfit just for hanging out with friends. The afflicted will also put-down others like sport.

I dunno, I guess he has best-dressed syndrome.
