I am a small adult. I liked them, with one exception: the built-in short lining for boys is clearly visible underneath, so I decided to send it back. The material is not transparent and does not shimmer through, it is a light gauze fabric that does not cover the integrated panties. It's probably fine for girls though. Very comfortable, both elegant and casual. AB is a great brand. The material didn't feel scratchy at all.
