Bell bottoms get a resounding NOOOO from me EVERYTIME. Usually, no matter who rocks it, it looks dated & just ewww. But Kourt K makes it look chic and sophisticated, which is hard to do with bell bottoms.
The key seems to be the flair & the tightness of the jean in the thigh. If the thigh is too tight you will most def end up looking like Thelma of Good Times: tacky, by 2011 standards [because Thelma was IT for 1976, the key being for 1976].
If u look at picture #3, that, to me is borderline excessive flair, that look is not my favorite; the 1st, 2nd & 4th pics show a perfect pant leg: straight, not tight in the thigh, moderately wide, draping over her shoe. I applaud her, this is how it should be done.
