My daughter wears a size 5T but I got this for her in size 6-7. The smocked dresses tend to fit a little more tightly, and I want her to be able to wear it for a couple of years. It is a tiny bit loose on her and long, down to her ankles. It is her favorite dress and she picks it out every Sunday for church. It looks great with ankle boots and gold jewelry. She gets many compliments. I wash it inside out and hang to dry, and it has held up great.
