I have recently discovered what I consider to be my very new favorite pair of 'black pants', the Lauren Moshi Bell-Leg Zebra pants. I am totally aware that this is not the pair of black pants you'd wear just anywhere (e.g. at work), but still, I think it is a very stylish fitted pair of sweatpants you won't just see on anyone (and yes, that matters.)
Those sweatpants are made of heavy soft cotton, are quite unique with the zebra print on the back of each legs (haven't you ever dreamt of being followed by zebras???) and are as long as you want them to be (just use a pair of scissors to hem them). They are perfect to work out or to lounge -in style- at the terrace of a café this weekend. And yes, everyone will ask you where you got this pair of gorgeous sweatpants...
