thanks all, as an update I bought my daughter the adjustable waist jeans at Lands End and the 7s fit for NOW. They probably won't in two weeks. They're tight around the waist but not uncomfortable yet. The 8s are falling off her and about 6 inches too long (the 7s are too long too). I'm saving the 8s for later
Now my poor son, her twin brother, who is the exact opposite problem as many of you have mentioned. He's also 7 but tall and super thin. He's been wearing size 6 slims from Gap and Gymboree oh for about the last year and now suddenly they are all two inches too short
Poor guy. He's easier though because he doesn't care what he wears and he's a solid "slim" so i'm sure i can get any 7 slim to fit him.
I love the slims and husky's however my daughter is just somewhere in between
