I bought 3 in green white and pink, one 3t and two 4t for my 4 and half year old. She is very tall at 36" and even the 3t fits to her ankle. I can never buy jeans for her because she is too slim for 4t jeans, she can fit in 24 mnth to 3t jeans but they reach to her calf. I love that these reach her ankles. I would have want it to bean inch longer but I have a feeling the 5t would be baggie on her. the 4t fits just right with no stretching at all, its just right for room to grow.
