"My daughter searched through the costumes & decided upon Kit the Cat. We ordered a size 12/14 in this product online knowing that costumes are usually made smaller than normal. When the costume arrived my daughter tried it on & found that the arms were way too small. She is an average sized 10 year old & the costume's arms would barely fit a 5 year old's arms. The costume itself fit, but we have had to cut the arms off the costume for her to wear it. Next time we will buy from a store where she can try it on first."
