The No3 that we got is just right for a 3-year-old child. The hat, for some reason, is not pure white as it appears in the photo, it has a yellowish color as if it has been on the shelf for a long time or maybe the material is different. Whoever buys it, I think they should get the next size up from their child's age because the fit is a bit tight. I hand washed it because I was afraid it might dissolve in the washing machine and already the cross on the hat got a little messed up. Other than that, it's a good costume for its purpose.
