"Blues like navy and cobalt are trending for grooms, and with tuxes, trimmer fits are being requested across the board," says Kevin Rome of Rome's Tuxedos. "Navy and blue tuxes are popular for a little more flash." The Blake navy tuxedo by Ike Behar features Super 120s wool, a black satin lapel and a single button closure.

"Fun socks are very popular, especially in a crazy color," says Chad Olivier of Iron Horse Clothier. "They're a great groomsmen gift. The colors range all over — pink, novelty socks with flamingos, fleur de lis and on. Crazy socks are mostly worn with suits — most grooms still wear classic black socks with a tux." Knee-high patterned socks by New Orleans-based CheckerBox are made with a cotton or cashmere blend and a custom elastic that helps socks stay up all through the big day.

"The big trend surprise has been the Brackish bow ties made of real feathers," says Kenny Rubenstein of Rubensteins. "There's been much more of a 'millennial' look in the sense that grooms now want to recognize their uniqueness, and they're doing it with accessories." Styles like the Rice tie by Brackish are a modern take on the classic formal bow tie.

Brightly colored ties like the Chisolm design by Brackish are being worn by grooms who choose to wear a suit rather than a tuxedo.

The Whitehall tie by Brackish gives grooms a classic style with modern sensibilities.
