Heigh ho, heigh ho
I'm including tan in shades of brown.
The only idiosyncrasy I consider an idiosyncrasy is my avoidance of gray suits. Everything else is a mild variation of preference that doesn't impact my dressing or purchasing habits much. I dislike flap pockets on anything but suits (feels messy and distracting, and since I often use my pockets, they get annoying in general). And you all have to admit, monks are like the most archaic looking thing folks...
