I mean, don't get me wrong, a well fitting pair of jeans with a killer pair of boots is awesome. But I prefer dresses! They're just more free and feminine. And what about the different cuts and styles? I mean strapless, backless, shirt dress, slip dress... LBD!
So much more versatile and easy to accessorize as well. Oh God, don't get me started on the accessories.
The right dress beats jeans any day. You don't see them wearing jeans on the red carpet!
