I tend to switch it up on a day-to-day basis. Today I wore red, blue, black, and white. Yesterday it was navy blue, sky blue, and white. Day before it was navy blue, light gray, and red/brown. Before that it was green and white.
I just wear what's in my closet that matches and looks nice, I dunno. I try to match the shoes too, so when they don't match I just go for white shoes or plaid shoes.
