Congratulations! I'd vote for lavender for the actual wedding ceremony and the red one for the party. That way she can both please those who'd like to see a virtuous maid at her precious moment and yet let her vivacious personality show. Gray sounds more like an office outfit.
BTW I saw an elderly gentleman in the local swimming hall sauna, which seems to be a meeting point for many of his age. Anyway, it was obvious that he had shaved his private parts. When the other geezers asked him for the reason, he gave this answer: If little Willy doesn't want to stand up when needed, no way he'd deserve a soft underlay!
