I'm looking for recommendations for shops with a good selection of Jr. Bridesmaid dresses for a 13 year old.  We'e been to David's and a couple others, but she's right at that in-between point where the Jr. Bridesmaids stuff doesn't fit her anymore but all of the adult bridesmaids dresses are too mature for her (read: her dad).  
Does anyone know of any places with a large size range for the Jr. Bridesmaid styles?
Thanks in advance for any leads!
