I ordered these tights for my daughter and followed the size chart to find my daughter's size. I ordered leggings in a size 10-14 which are suitable for weights up to 110lbs. My daughter is 12 years old. When I took them out of the box, it seemed to me that they were small, but I didn't really care. I washed them this morning and tried them on my daughter and you can imagine how it turned out! Shown here are white leggings over a pair of blue size 14 for reference. The packaging also clearly states that it is true to size.
