"We love this costume! I was hearing horror story reviews about costumes that are way too small, so I made sure to order big. I have a tall almost 2 year old and ordered the size 4. It's a tad big but it'll work, plus room to grow for more dress up fun besides Halloween. This was a bit more than what I wanted to spend, but I think it'll be worth it. Very good quality. Our active toddler loves it!"
