That is so funny! I agree with you on the Nordstrom thing. I love Nordstrom clothes, but I went to buy some trendy underwear for a tweeny once and all they had were thongs! NO NO NO Way! I'll let her make her own choice about that later in life LOL. Anyway, have you tried Limited Too? You can find the store at Clackamas Town Center Mall. They have all the trendy stuff that tweenys are into, but they are cute AND respectable.
Oh and I almost forgot, OLD NAVY. You can even shop for youself too! They have trendy stuff from infants on up.
