Review on Toddler Mermaid Costume Birthday Halloween by Larry Breeze

It's great but WAY small! My daughter wears 6 but all her dresses are very loose on her. I got 5/6 and it was very tight and also too short. The good news is that my youngest daughter's top fits with a little more room, but she wears 2T! So if your kid wears 3T or 4T and is very skinny, a size 5/6 should be fine. Otherwise it doesn't work.
