I'm having such fun thinking out all the details of me wedding even though it's over a year away! Fi gets irritated when I want him to discuss details that have no relevence right now, so I'm going to toss this out to all of you

We are thinking of having our colors be dark blue with creamy yellow and bright/mediumish pink as accent colors. (OK, read "we" as "I decided and he agreed") We'd like to have the bridesmaids in dark blue/navy. Fi and some of his groomsmen will be in Army dress blues, which include a black jacket and blue pants.
We'll also have some civilian groomsmen, either in tuxes or suits (not sure which yet.) So... navy blue suits? Black suits? Black tuxes with...what color vest???
What would you do?
