• Novelty neckties. As much as you want to show a glimpse of your childhood to look younger, I’m afraid that won’t work through pulling off ties with cartoon prints. At this age, your ties should have a hint of elegance and should be made of silk.
• Overly trendy hairstyles. If you’re losing your hair, any style that’s more than a half-inch long is a big NO.
• Baggy clothing. They look awkward and will make you appear even older than you already are.
• Tight clothes. It would really be too hard for older men to move comfortable in skinny trousers and a very fitted shirt.
• No belts are required if you are wearing tuxes at weddings. However, a cummerbund or a waistcoat is a must. Just don’t wear both at once.
• Hawaiian and Camouflage Prints. 
• No ripped jeans.

Show a glimpse of decades past with your wedding attire. Vintage weddings involve colors and patterns in ways that make them distinct from traditional ceremonies. This is the perfect time to show off your unique accessories, like cufflinks or a boutonniere lapel pin. Opt for an off-white or ivory suit, but keep in mind to carry a humble ensemble because, after all, the spotlight should be on the groom and not on you.
