For an UO, it's not bad. It's geared toward students of course so the selection isn't as "edgy" as one might hope. Plenty of nice stuff at prices that won't totally break the bank. Hipster-y, yes, but it also fills in the gap that Marrakech, Paris' Boutique, etc. have tried (and failed) to fill over the years. As campus is waaaay far from the Goodwill and even downtown Champaign is a considerable trek, UO gets points for sheer convenience. They're open til 9pm most nights so if there's an emergency run for shoes / date threads / a dress for whatever formal stuff goes on in college, UO is a pretty safe bet and it's closer than the mall.
The staff is very sweet and helpful, the store is kept organized and the sale section is a permanent fixture.
And the big upside for the skint populus is that a lot of used UO clothing will land itself in our local Goodwill for a pretty nice price.
