I like that they are thin. I didn't have to pull my waist in as much and my legs aren't baggy. We have a problem that the waist is always big for the length we need. My two daughters fit a size 8 Slim. They are 8 and 10 years old. My 8 year old girl has long legs and I still had to tighten my waist but not by much. I like that it has an adjustable waist. The color is great and goes well with her school uniform. The quality seems good and I'll update if it turns out not to be.
