I bought two of these for our granddaughters. I always stuff a Thanksgiving dress in her Halloween bags and I think these are cute well tailored dresses for this year. Size 6-8 fits our 7 year old who is 4ft tall and weighs almost 50lbs. Size 4-6 fits our 4 year old who is 3 1/2 feet tall and weighs about 34 pounds.
