I really do not know where you could find what you're looking for, except maybe online. However, I would recommend something that I hope does not offend you. Please look at your daughter's diet, exercise level, etc. & make sure you are doing everything you can to help her be healthy. You have one issue in that you cannot find clothing to fit your daughter. Yet you have a bigger issue in that your 8 yr. old daughter is on the slippery slope to becoming a very overweight adult. Again, please don't take offense...
