Weddingbee boards

A few of my bridesmaids and I are meeting in Chicago next week to do a little bit of bachelorette party-ing and, most importantly, looking for bridesmaid dresses! However, only one of the women is from Chicago and everyone is pretty clueluess about all of this wedding stuff. So I've been browsing the Knot and Google-ing, but ultimately I have no idea where to even start looking for a place to go shopping! We're looking for a place that offers dresses on the cheaper end of the scale, even though we probably won't be buying this weekend I'd rather we start looking at cheaper dresses rather than falling in love with bridesmaid dresses that will cost more than my gown! Oh, and props to places that will let us take pictures - I like pictures :-D

So, any Chicago-based women out there have suggestions for a great place to look at bridesmaid dresses?
