If your fiance does just one thing before meeting you at the end of the aisle, it should be to click through this gallery for a groom's guide to style.

"You don't have to have a suit or tuxedo custom-made to guarantee a good fit. Buy one off the rack, then take it to a talented tailor for fine-tuning. What you wear at your wedding should become a wardrobe staple that you'll reach for again and again," says Downing.

"You're going to take your jacket off at some point, so it's crucial that what you're wearing underneath fits you to a T. I always recommend Ermenegildo Zegna's French-cuff shirts. White is a safe choice, but a pale-nude color is nice, too." Available at neimanmarcus.com.

"Cuff links are so elegant -- period, end of story. David Yurman, John Hardy, and Konstantino all offer attractive styles you can use long after your vows."

"This Gucci jacket is a standout from the fall runways. Velvet -- though not for everyone -- is best in a formal environment, especially in fall or winter. But regardless of the fabric you choose, it's really about the shape: fitted close to the body." Available at select Gucci stores.

"Black ties are smart, timeless, and always appropriate for a wedding. I love this Charvet version, which is made from luxurious silk faille. The matte finish with a touch of sheen looks terrific no matter the season or formality." Available at bergdorfgoodman.com.

"If you feel more like yourself with longer neckwear, black satin is the classic choice. However, a color that recalls the bride's flowers or the bridesmaids' dresses can be just as put-together. You can't go wrong with something from Stefano Ricci or any of these from Charvet." Available at bergdorfgoodman.com.

"A glossy finish is key for formal footwear. These, by Salvatore Ferragamo, are also incredibly comfortable -- extremely important when you're going to be on your feet for hours. After the wedding, wear them to work with a dark suit." Available at neimanmarcus.com.
