I was searching everywhere for a "7" which, apparently, doesn't really exist.  These fit like everyone says which is exactly what I was looking for.  A "6" was too small for our very tall 6.5 year old but the "8" (apparently the next size) was ginormous on her.  So, instead of having her go commando, we tried these and they are perfect!  The low rise and the tendency to run small makes our kid well-fitted and not "picking panties out of her bottom" all day.  A big thank you to the other reviewers!
