The Groom almost always will wear a different color combination than that of the groomsmen. The color difference will create a beautiful color contrast towards the wedding party. The bridesmaids and the groomsmen shirts or outfit can be color coordinated as well. You can choose for the Groom a darker color linen suit or a shirt depending which clothing style you have chosen for their attire. If they are going to wear suits then make the groom a shade darker than the groomsmen. If they are only going to wear Guayaberas or Wedding shirts then have the groom wear a stronger color than that of the groomsmen.
