I ordered this for my daughter to wear under her halloween costume. She is going as Ariel from the little mermaid and it's too chilly for her to wear just the seashell top and the only leotards I could find in stores were not only short sleeve but they were either pink or black. I was stoked when I found this on Amazon and for such a good price! My daughter just turned 5, she's a little big for her age(more the size of a 7 year old). Never purchasing a leotard before I googled this leotard and went to another site to figure out how to determine size. I got out the measuring tape and measured everywhere it told me to and got the size she needed accordingly. I must say their size chart is right on the money, this fits her PERFECTLY. It's a really great material, nice and soft cotton type lining on the inside and soft and slick on the outside. It's nice and THICK. Much better quality than those you would find in Wal-Mart or Target for sure. I would recommend these to anyone and I will be coming back and ordering more this summer when I put my daughter in ballet :) Also it came extremely fast! Very pleased.
