Not too many Padres related Halloween costumes this year, but the two that I saw online were quality. I'll take quality over quantity any day, unless we're talking about hot dogs.
First "Tony Gwen Stefani" as first seen on LobShots.com. Very creative. I like a good mish-mash costume.
And Jeremy, author over at Friarhood dressed as the Swinging Friar. A classic look for any Padres fan. He says he'll get a real tonsure cut if the Padres make the playoffs. We'll hold him to it.
