I ordered this for my daughter who is 8 and 1/2 and wanted to be Cleopatra this year for Halloween. The reviews were so wonderful I chose this one. We ordered the Large, (which Im really glad I did) I was originally going to order the Medium, which is 8-10, but when I called Party America the woman who answered the phone told me it ran small, so I would want a Large. My daughter is about average sized for her age, (a bit short), wears size 10 pants and size 8 blouses. The dress just covers her shoes. I might need to safety pin it up a little, but this way she can wear snow boots if need be and it wont' matter bc they won't show. The quality is very nice for a costume at this price. I would recommend this. :D.
