To start your day in a relaxed mood, choose to wear a casual outfit featuring one of the hottest trends of the moment: the number print t-shirt, for a sporty chic look. The basic rules for these tees are: they're larger than average (pick a larger size to make it look as if you stole it from your boyfriend's closet) and you are supposed to mix them up with something extremely feminine, just like high heels and a clutch.
