We get married three weeks from tomorrow and my 78 year old dad went to get fitted for his tux this week. He decided to get a royal blue vest and tie which doesn't at all go with our wedding colors. We only have a best man and MOH and they are in pale pink. Our venue decorations are pale pink and fuschia. The question is do i leave him be because he is 78 and doesn't know or care much about fashion or ask him to change it? I wouldn't care but am afraid it will look funny in pics.
