I had regretfully disregarded reviews saying they were too thin and ill-fitting.  Although they *look* okay, I have 3 major problems with these:
1. They sound like wind pants when you walk.  This is a problem for me, because I'm not an 8-year-old boy.

2. I am 5'9", 150lbs and the large was much too small.  I'm pretty slender through the legs and normally wear a medium sized bottoms, but I got a large after reading reviews saying they ran small.  Instead, the leggings stop 3-4" above my ankles, limiting the kind of shoes I can wear them with. Furthermore, they seem to be the kind of pant that is symmetrical front to back (i.e. you could wear them backwards and it'd be the same fit as wearing them frontwards), meaning there is far less cloth available in the butt area.  Given that I, and most women I anticipate would want to wear pants of this trend, have a butt where a butt should be, and not a front-butt, they squish the butt and thigh together in such a way as to highlight every dimple and patch of cellulite on the back of my legs.  Cute, right? Which brings me to my next point:

3. They really are too thin.  And not thin in a tights-ish kind of way, where at least your legs can breath, but in a suffocating, crusty way.  It's as if someone took a pair of tights and sprayed them down with some sort of rubber finish.  I haven't worn them out of the house yet, partially because I'm afraid if I bent over too far, they'd split down the middle.  I'm hoping if I wear them enough they might get a little more give to them, and my legs would look less like old tar and more like legs wearing leggings.

If you are expecting a legging-like material, these are not it.  Although I'm sure I will get some use out of these, they won't be a staple in my trend closet.  In hindsight, I would've either spent more on a p/leathery pant or spent more time finding a better quality legging.  I would realistically only spend $10 on these, and I'll update this as soon as one of my drunken dance moves causes the leggings to burst.
