A funny video has emerged from the US of a little girl attending her ballet class dressed up as a hotdog.

The footage, captured in Austin, TX, shows Willow standing out from her classmates - who are mostly dressed as princesses - in her unusual costume.

''The girls in my daughter's dance class were all asked to dress up as whatever they want, with an emphasis on what they want to be when they grow up,'' the filmer wrote online.

''My daughter has always been incredibly strong-willed, and decisive.''

''There was really no negotiating about this outfit, regardless of how hot she became the more she danced in it,'' she added.

The girls in my daughter (Willow's) dance class were all asked to dress up as whatever they want, with an emphasis on "what they want to be when they grow up." My daughter has always been incredibly strong-willed, and decisive. There was really no negotiating about this outfit, regardless of how hot she became the more she danced in it. I have another video or two or her going through some of the dance exercises as well.
