Little boys may like children's fancy dress, but the costumes aren't usually pink and frilly.

However, one little boy in Seattle is challenging stereotypes by proudly wearing what are perceived to be outfits for girls.

Dyson Kilodavis, five, showed a preference for dresses from an early age, but his mother Cheryl tried to discourage him for fear he would be bullied.

However, after realising he was unhappy, she relented and has now written a book about her son entitled My Princess Boy.

She appeared on US TV programme the Today Show this week in the hope of spreading the message of acceptance - and presumably raising the profile of the book.

Dyson happily wore ballerina fancy dress for his first appearance in front of the cameras.

This may be a phase, but it is one he might not necessarily grow out off. In November 2010, a grown man dressed as a princess won the UK's national Scrabble championships, silencing his critics for good.
