A friend of mine got married in Teheran and her wedding was one of those three-day affairs with a photographer attached. She said everyone there carries nice faux bouquets because real flowers wilt in that weather pretty soon. Definitely won't hold for a full day.

I like paper flowers if you are going to go the fake route. They're pretty and cool looking but don't look like you are trying to pretend they are real.

I think the pink ones are really pretty. However, IMO, they start looking dingy in a matter of months, not years. It is really hard to clean the dust off and it will even settle on the fake "water" (resin).
