I have this habit lately, I can't shake it. I've been rolling up the sleeves of every shirt I wear. It just so happens the nonchalant rolled sleeve style is in vogue, but for me, one who sits at a computer all day, it's purely functional — I swear! No, I jest — it's totally cute. If you feel me, consider a rolled-sleeve cardi. The cardigan is another at-work style buddy, so it's double the function, double the fun.
