This medieval knight on a horse looks like he just walked out of an historic painting. Wow. While this knight Halloween costume obviously befit senior men, it would look equally charming on a crowned princess or young prince, with a nice feather on his hat.
A reader asked me where to buy the horse, and the answer is that there are many different kind of toy horses you can simply order online. Easy.
