It is traditional for Scottish grooms to wear kilts, but the newer western tradition of suits or tuxedos for men is common now. If your groom is up for the challenge, your guests will certainly be charmed to see him and his groomsmen in kilts, and your wedding photos are sure to be more colorful than if the men had worn dark suits. Even if your groom chooses a suit, you can consider enhancing your Scottish wedding theme with plaid vests and neck ties.
