I don't know if I'd call my husband rockabilly, but he wears the Daddy-Os bowling shirts and creepers and in the wintertime, a porkpie hat. For him, it was an accident. He's big into swing music, as well as some of the rockabilly music, but hates "dressing up". The only trousers he owns go with the tux he wears once a year. Once he saw Charlie Sheen wearing bowling shirts on Two and a half Men, he had to have those shirts. Now, everyone gets him a bowling shirt for birthdays, Christmas, ect.
