Yes, at every wedding, all eyes are on the bride. But that doesn't mean the groom has to blend inconspicuously into the march of the penguins—we mean groomsmen. A tuxedo that matches and enhances your groom's body type can take him from merely suitable to perfectly suited—and make him almost as much of a star as you. We recently sat down with Nickelson Wooster, men's fashion director for Neiman Marcus and Bergdorf Goodman, who offered his recommendations and tips for finding a perfectly fitted look.

For a Short, Broad Body

A single-breasted peak lapel tux will "de-emphasize a thick middle," says Wooster.

For a Short, Slim Body

A single-breasted peak lapel tux helps to "draw the eye upward, giving the illusion of height," Wooster says. He adds that a thin, short guy can wear a shawl-collar tux as long as the shawl collar is not too wide, which can draw attention to a lack of height.

For a Tall, Muscular Guy

A single-breasted notch lapel tux works perfectly on a broad, brawny type. "It's a can't-go-wrong pick for just about any shape," says Wooster.

For a Tall, Thin Guy

Lanky guys are the luckiest: "You can wear basically anything," says Wooster.

For a Guy Looking to Slim His Silhouette

Wooster's ultimate streamliner: a single-breasted peak lapel tux by Tom Ford. "The way he cuts it is so elegant; most guys fall in love with the jacket shape," he says.

Must-Have Tailoring Advice for Every Groom

"Pants should come just to the top of the shoe," says Wooster. "The jacket sleeves must allow for one-quarter to one-half of an inch of the white French cuff shirt to show."

Investment Tips for the Guy Who's Buying, Not Renting

Wooster advises purchasing "a classic black tuxedo in a super 120's or better fabric, which is seasonless. The lapel should be satin or grosgrain." And he cautions against trendiness: "Do not try for a 'fashion' tuxedo," he says. "Go with the most classic style."
