Hot Topic is an awesome store, if you are the type who likes black, studs, and heavier music. Or if you like fairies and retro clothing (think Rainbow Brite, Care Bears and various child faves, if you are a 30something).
I often can shop off the rack, even as a plus sized chick. The clearance items are at a price you can't beat.
They also carry alternative hair coloring kits and make-up.
They may not be everyone's cup of tea, but if you tend to have different tastes you will probably find something you like here. My only wish? that they'd make the stores less cluttered looking.
