"It is exactly what my almost 4 year old wanted! We compared many mermaid costumes online and read reviews, which helped with our decision. Wanted to give feedback on how beautiful the costume is, the tight fitting reviews are so true (my daughter is 29lbs and 37in tall) and she barely fit into the toddler 2-4 costume. We put it on right away and love it but I am hesitant to let her play in it until after halloween because the seams do not look like they would hold up in play for long."
