The dress, to dog and the guy. It is a rainbow wedding- bride in the dress with the groom matching his hair to the dress and the dog as the BM.
Of course if the bride wants a Rainbow Lady Godive wedding- she could use the dresses for the BMs each with a mathing poodle with the groom matching his hair to the dresses and the bride in all her glory have her hair to match the grooms under her veil with rainbow heels. You wouldn't want anyone to steal the bride's thunder.
It would be the wedding of the century!
