Your clothes introduce who you are before you introduce yourself. So make a statement. Personally, I'd like to make an entrance at every venue I venture to a la Barbra Streisand in Hello, Dolly!—grand, red carpeted staircase and all!
If you haven't seen this movie and you are in the mood to sing along and you enjoy vintage movie musicals made in the 60's (this one's directed by Gene Kelley of Singin' In the Rain!), Hello, Dolly! is a great watch!
