tweed vest and different color tie.for mine maybe in the black or dark grey color scheme in cool prints. Why not have your Groomsmen wear the same vest/tuxedo, but all with different ties in the same color?
Light grey for groomsmen and darker grey for groom! I love the idea of the groomsmen in a different color suit than the groom! Only the groomsmen would have the dark gray ties and the groom the lighter.
