Doug Dimmadome is the wealthy, booming businessman from Nickelodeon's animated series *The Fairly OddParents*. Famous for his catchphrase and his impossibly tall hat, he is a favorite choice for nostalgic cartoon fans looking for a funny, high-impact costume. The look centers on an all-white western suit, a bolo tie, and a comically oversized white cowboy hat.
