Bought these for my son's dance class. Although the above description says "Children's" the website had them strictly labeled for "boys." I wasn't familiar with what the size "I" meant, so I called the store and they said it was equivalent to about a size 6. When we tried them on, at times the flare on the legs looked fine and then it looked like a girls' bootcut style. However, his dance teacher approved them, thankfully, because they fit PÈFECTLY! I got a great deal on them because they were the last of 4. Too bad he won't be able to fit them next year when he gets his growth spurt!
