Excluding underwear and socks, my entire wardrobe is earth tones - mostly olive green. I basically wear the same outfit every single day. I don't want to have to think about what to put on. Now everything I have goes with everything. When I take a clean shirt, I just grab the one from the top of the stack.
It has become a kind of inside joke. Whenever someone catches me with a new piece of clothing, they compliment my choice of (green) color.
