There's no more photographer more important than a wedding photographer. There are many events and situations where a bad photo can easily be laughed off. It adds to the experience. At a wedding, that's not the case. Everything needs to look perfect or else the wife will curse the husband with unhappiness forever. At least, that's what I read in an article on... let me check... it was Men's Right Monthly- oops. Maybe that article isn't as reputable as I thought.
There's nothing wrong with having a couple of little person bridesmaids, but I'm sure these women would rather not remember this day as the day they stood three foot five inches. Women already have to wear heels to be taller and thinner. This just makes the heels an entirely moot point. They'd need stilts.
