STYLETHREAD -- LET'S TALK SHOP!

Hi girls!  I'm done with my Houston project and am now in the Philly area (close to Malvern) for the next few months.  I need some ideas on what to check out in the evening and weekends I think I'll take the train into Philly on sunday afternoons.  Any cool shops, or shopping areas (besides King of Prussia Mall)?

Also good brunch places for when I come in early enough on a sunday?
