I don't know if I am too much of a trend follower (although I like trends but never wear them, sometimes) but gray has been one of my obsessions. It started in NYC when I needed a turtle neck gray sweater so I could wear it underneath a black faux fur coat (which never got any of those). 
And tumblr is certainly not helping. Gray is all over my social media channels and it is driving me crazy, not because I am tired of it but because I am so obsessed with it that I can't keep my fingers away from my laptop (broken one from apple, so THANKS!) to load some retailers websites!! 

Shop some grays!
