I was very careful to read the reviews and to pay attention to the measurements.  I bought these for a (7) year old girl and she is a little taller than most her age, and slightly slimmer.  She usually wears a 6x or 7 depending on length, but I bought these in girls' size (10) and they fit perfectly.  Again, let me say the little girl who wears these is slightly taller than most her age, but she is considerably thinner. These were only $10.99 for a (12) pack and they came very quickly!  I am very satisfied with this product except for the sizing issue. This is why I gave this item (4) stars in stead of (5), sizing.  She says the fit and feel are nice and that she likes them, but I would have been upset if they were too small and they would have been if I bought her a 6/7/8.
