I'm a long-time player, and have been kicking around an idea for awhile and finally decided to share it with you guys to see if it might be something you might implement.
How about fashion design contests where the players submit outfits that they design to be voted on by other players? The winner gets diamonds and the satisfaction of seeing their design made into an actual outfit that could be purchased piecemeal, won in mini-games, or earned via Marco quests.
I'd love to have this option and I bet other players would enjoy it, as well.
Thanks for taking the time to read this...
