Grooms aren't limited by the traditions and conventions that brides have to fight when choosing their wedding dress. If your wedding is taking place in cold weather, choose a suit made of dense materials like wool or velvet. For summer weddings, Bermuda shorts or linen trousers can be worn instead of classic suit pants. In this case, a suit jacket would look out of place and a light linen shirt with short or long sleeves would look better. In reality, grooms do not need to wear a suit at all. Parts of the wedding look can be purchased separately, but ideally, they would match to create a cohesive look on your special day.
