random trivia: what to wear to weddings

I received an invitation to a friend's wedding today. The invitation said "formal attire." Having not been to many weddings, I didn't know what that meant.

I tried to search for this term at Google and most of the search results were tuxedo shops or descriptions of different types of tuxedos.

But after trying a couple of other queries, I found a wedding website that appeared to be an authoritative source on wedding attire.

Apparently for daytime weddings, a "dark suit" with "conversative shirt and tie" is appropriate. Only when the invitation says "black tie" do guys need to wear their tuxedos.

Whew! And I thought I would have to go hunt down where I put my trusty tux...
