"I ordered this costume for my daughter to wear to her 3rd birthday carnival. She's only 3 but is tall for her age, and after reading the reviews for the 2-3T size I decided to order a 4/6 instead and it fits her perfect!! Costume is perfect! It matches the picture exactly. I've read reviews that it is thin see-through material, but I don't think so. I'm glad I ordered it a bit bigger though so my daughter can wear clothes under it for Halloween since I live in the midwest!! Overall very happy with this product and well worth the price!"
