pumpkin patch makes long skinny jeans expensive but very cute
osh kosh has skinny jeans that were TOO skinny for my skinny girl.
childrens place aren't super skinny but do have adjustable waistbands.
I find that pumpkin patch run much skinnier than gymboree
oops I just noticed that you want something easy to get on and off...I would say skip jeans and pants and go for leggings.
If you can afford it Tea Collection has the most adorable tunics and coordinating leggings.
Target has very cheap leggings that hold up pretty well.
I like to buy the Tea Collection tunics and then buy coordinating leggings from target (it's cheaper that way)
