I don't have multiple colors to match. The only socks I have that I have to match are for cycling. I have several pairs of the same pants in a few different colors, but they all match my polos so I don't have to worry about anything if I don't do laundry mid-week. I don't like wearing a shirt twice a week, I know I washed it, but the perception that I may not have washed it bothers me.
I also take my clothes out of the dryer and fold/hang while scorching hot to avoid/minimize wrinkles.
I'm sure there's more. OH! My meals are pretty much the same no matter what.
