"This costume was perfect for cooler weather in the Northeast. It's warm for indoors though so keep that in mind!
My son normally wears 18-24 months from Gap that fit slightly looser, but I went for the 2T in this costume and I'm glad I did. The fit was pretty much perfect with a onsie underneath. Just slightly rolled the sleeves. At 20 months old, he's in the 75% for height and weight. (Just a guideline.)"
