I ordered 2 of these dresses for my girls size 2T and 5. Clothing labels say 2-3 years and 4-5 years. The 2-3 year olds were definitely tall for my 2 year old, but the 4-5 year olds fit my tall 4 year old well and will probably last this winter and next fall. The dresses are comfortable and my kids loved them but I would advise being careful with the sizing. A few months ago I ordered another dress from this company for my 4 year old's birthday in a size 4 and it arrived in 3-4 years. He approached her, but turned out to be small.
