I'm not sure how I feel about the harem look - I doubt I could pull it off myself, but I know wide-leg jeans never go out of style.
Skinnies are quickly becoming a classic. Be it jeans and heels or a more daring stretch pant paired with a loose and layered top, not matter which way you go you're immediately chic.
All that being said, the look of opaque black tights combined with the uber-fabulous YSL heels is tempting me to break my pants habit stat!
