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?
It’s so hot now that I can’t imagine a groom wearing the whole suit with a vest and jacket – that’s kind of crazy! So how about a cool groom look without a jacket? There are several options: wearing a vest, wearing just a shirt with suspenders.
Love this look for a summer wedding. I'm sure no guy looks forward to sweating in a suit a jacket under the hot summer sun. This is dressy enough for a wedding, but cool enough for the summer heat. Great sleeve length, more formal than a short sleeve.
