Never been in one before.
I'd define it as a place that lets me try the trends without a financial commitment.
Definitely sized for skinny girls (I'm not one)
Missed the upstairs, after reading Connie T's "the upper level also feels a bit too -I'm an adult and need shiny clothes that look complementary to the metrosexual clinging to my side." Now I'm curious.
Got some skinny pants, and a tube skirt for less than $20.
They only have to last as long as the trend.
