I've been wearing these cute knee-high rainbow socks for so many days now, I can't even remember the last time I washed them! They are really starting to develop quite a pungent odor. That's not a problem for you though right? The dirtier the better right? Plus the nastier my socks are, the smellier my feet are underneath. Would you like to see how gross they are? I'm sure a foot slut like you can't resist.
