Standard Softball Pants. The size is absolutely terrible. I don't think I've ever seen such large sizes. I read that the pants have become too big, so down a size. I bought 6x for my daughter who will be 8 in 3 weeks. She usually wears a size 7. Her waist was so big that you could pull out a few more inches. Not sure my almost 8 year old could wear a size 4 in these pants. Conclusion: The dimensions do not match these so much that I would not even try to speculate. Choose another brand.
