I still like my EF butt vest, even though I haven't worn it a ton this year. I don't know why it kind of works on me, because miniskirts are horrible on me. Maybe because the leggings are more substantial than tights. And I tend to wear these with slightly looser, longer tops, for a long-over-lean silhouette.
Contrary to what LP mentions about the one-piece thing (fit variables), I find the skirted leggings much easier and comfortable than any skirt and tights combo I've ever worn. It's stretchy, so the fit works even when my weight varies, and it's all one piece in one fabric, so nothing is rubbing and riding up or down.
