See the groom without breaking the "groom shouldn't see the bride before the wedding" rule! - these pictures are adorable. Love this idea! Although I think it's a little unfair that the bride can see the groom - maybe blindfold both?
For before the ceremony - bride and groom reading letters written to each other - would make a really cute picture after side by side. -I'd write the letter the day on engagement then read it on the wedding day
