My daughter has 3t/4t depending on the brand. But I noticed with the dress sizes that it's smaller like 2/3t. She weighs no more than 35lbs and is 3 years smaller than normal and we wanted the dress to fit perfectly so we went for the 2t, it didn't fit her for a long time but the size was perfect for her, a bit bigger her knee and the dress is very cute, doesn't look cheap and can be bagged! Highly recommended, she feels like a princess in it.
