My daughter usually wears an 8 Slim. these 8 are too tight for her but the perfect length. definitely 1 more if lean, or 2 more if stocky. We're trying 10's and hope they aren't too long because she really likes the fabric and the style
Pros
I wish they were in women's sizes! Great fabric, good quality and light weight for my 4 year old!
Cons
Pants may not be appropriate for students with mobility issues or mobility issues who require special clothing adjustments.
