All white wedding? ....?

My wedding colors are pink and white....I was thinking as the bride a white wedding dress and the bridemaids white with a pink sash,the groomsmen white tux with pink vest and tie,but what about the groom? He wants to stand out from the groomsmen but I think if he wore black it would throw the whole thing off!....any suggestions? I was thinking a top hat but idk if that would just look silly...
