What can I wear for a March evening country club wedding in Palm Beach FL (Black Tie Optional). Would a white dinner jacket be appropriate?

I think a white dinner jacket would be very sharp! As you know, in FL, the white rule is rather nebulous.

Are you thinking a dark pair of pants to go with it?

Thanks for the advise. I was planning to wear black tuxedo pants and a white formal shirt (with studs), black bow tie and a black silk pocket handkerchief.

Wow. Yeah, that will work. ;) Don't you love living in Florida in the Spring! :)

It sure beats -4 degrees wind chill here in the Northeast!
