The product itself is good quality. My daughter is usually a size XS to S or size 1 to 2 in regular clothing  She is 5' 2" and weighs 102 lbs. I ordered her a size Medium after reading other reviews. I am so glad I did as they are a great fit. The length is about 3-4 inches too long so I will be using the iron on hem so we can lengthen them as she grows. I agree with the other reviews that say they are very small in waist and long in legs.
