I think you can look for dresses in any online store, but if you need to find exactly the dress of excellent quality I recommend you pay attention to hanfu clothing. There are lots of different hanfu dresses including children's dresses and I think you could choose something there. You can also combine maxi dresses with long sleeves with ballet shoes to create a comfortable look both during the day and at night.

Thank you so much for the tip. I will definitely use it and place an order
