Best place to get outdoor gear for someone only 5' tall?

I’ve got about a month until my trip, 8 days on the A.T. in Shenandoah, and I need some gear (I usually camp during the summer, so I’m lacking in cool/cold weather gear). I’ll be trying on some stuff at R.E.I. and Dicks, and I’ve been looking at Cabella’s, but no one caters to we wee folk (I’m much too, um, well-endowed to wear kids stuff). Any suggestions?
