A very dapper Prince Harry and Prince William have been photographed on the wedding grounds, walking alongside each other in pretty similar suits.
It appears Prince William at least has coordinated his red tie to his wife Kate Middleton's light pink dress:
Perhaps there's a hint here too, from the color of the light vest and tie Prince Harry is wearing, what color his dates Meghan Markle is in. The actress hasn't been photographed yet.
The princes' light vests and pants are also similar to what James Middleton and Spencer Matthews, brothers of the bride and groom, are wearing—so either it's a hint they're all part of the grooms' party or just fashion:
James Middleton and Pippa Middleton\'s mom Carole.
