i put a lot of em's old clothes on ebay this week. they are all sizes 5-8 and they fit her over the past 1.5 years or so. so i would say the 5s run a little big and the 8s pretty small.
if anyone's interested, i started the bidding at $5 and only have 1 bid. shipping is $25. there are over 70 pieces in the lot and i'm including whatever gymbo matching bows i can find.
pretty much everything is either gymbo, gap, old navy, target. all seasons.
