I am going to differ from the others and recommend UO. I like UO because I can get trends ahead of time (they had skinny jeans very early on and I got a cape there last year) for not a lot of money. However, their stuff is very casual. It is not office wear. If you are looking for a weekend skirt, I'd go for it. If this is for work, look elsewhere (unless you work in a very casual environment).
The fact that the skirt has been around for a while with lots of decent reviews means people must be happy with it.
I've been loyal to UO since the 80s when I was in my 20s shopping at their NYC store. I walked away from them for some time when they became too young and ironic but I have been enjoying some of their things lately like their inexpensive colored denim and great slouchy tees (perfect for lounging).
