A wedding is one of the few occasions where everyone remembers what you wore — so it is worth getting it right.
If you are the groom, a three-piece suit or a tuxedo in ivory, beige or midnight tones makes a statement without stealing the scene. Groomsmen should coordinate with the groom's palette while keeping their own fit sharp.
As a guest, take your cue from the invitation. Formal evening weddings call for dark suits and polished shoes; daytime or outdoor weddings welcome lighter colours, softer fabrics and a modern fit.
Whatever your role, a few rules always apply: a crisp shirt, a tie or bow tie that complements rather than competes, and shoes polished to match your belt.
Above all, wear something you feel confident in. The best wedding look is the one you forget you are wearing — because you are busy enjoying the celebration.
