As other reviewers have said - I almost always walk out of this place with something. They have a great collection. For second hand their prices are not cheap, but usually reasonable. I especially often find good shoes here. It's also good for kids clothes.
I sell new stuff there every season and make a decent amount. Naturally I take the money and go spend it right away in the same store! What I will say about it is that bringing your own clothes in to sell can be hit or miss. The girls working there are very strict and there may be a lot of stuff you love and find beautiful that you are even reluctant to sell, which they will take one look and shake their heads and put it back in your bag. So note to self: skip bringing your clothes in on a day you're feeling gloomy :)
For the rest there is usually nice stuff hanging so you have to give it a try. It is not a beautiful store with any kind of lovely or fancy decor, so at first glance it really doens't tell you that it actually has great stuff hanging within the racks. Go there with a bit of time on your hands, the energy to dig a little, and preferably without your kids along (though if you must do the latter - there are a couple of small things downstairs which they can play with...) read more
