'Morning Dress' consists of three elements; the morning coat, waistcoat and trousers.
The Morning Coat is longer in length, and cuts away at the front.
The Waistcoat beneath, tends to be made from a different cloth, in a contrasting colour; a popular choice is linen or a twill weave cloth.
The Trousers to morning dress are always brace trousers and are traditionally in a black and grey stripe cloth; however, it is also correct to have them made in the same cloth as the morning coat.
