What to wear to a wedding?

[Jock Scot]

I've always been told, if it is being worn by the groom, it is properly referred to as a mourning suit.

Maybe you are right, but I think not! Morning(as in good morning)suit is how the collective knowledge of this house spell it---eight people. Mourning implies a death in the family,on second thoughts, some would regard a wedding as almost the same thing!! That is not how morning suit is spelt in this house anyway!
