Painful though it may be, jeggings have legs. Whitney Port wore the scary legging-jean hybrid to throw out the first pitch at a Dodgers game in L.A. yesterday. She has the killer legs to pull them off, and they still don’t look nice. Or cool. With luck, this garment will only survive part of the season, like those horrible wide-leg yoga-gaucho pants that never should have been popular a couple of years ago.
