Tux
The style of suit will depend on the formality of the wedding. A beach wedding lends itself to a fresh linen look while a more formal affair might call for tails. The time of day and the season will have a bearing on your choice of suit and accessories, so keep that in mind if you’re considering a top hat for a breakfast reception or an overcoat in the middle of summer. Try the International Formalwear Association Tux guide for more info.

Color
Tonal shades are very fashionable, so you don’t have to keep to black. Smoky blue, charcoal and subtle greens are fresh alternatives to the black suit. Have the bride take a swatch of material from the bridesmaids’ dresses for you so you can make the perfect match. Tone your shirt with the color of the suit for an ultra-smooth effect.

Hair
Get your hair cut no later than a week before the wedding. That day-of haircut says you're a last-minute man. Don't be afraid to try that stylist your metrosexual buddy goes to. The wedding only lasts a few hours, but the pictures will be around forever. Look good.

Shoes
Patent leater or Faux Patent? Take your pick, both can look good. Our advice: No wingtips.

Groomsmen
Allow us to state the obvious: make sure they all match. There's nothing wrong with letting them wear their own tux, just ensure it looks close enough. Also, involve them in the process and don't be a dictator here. Just because you think the pink cumber bund looks good doesn't mean they will.
