A Few Tips...
A black herringbone or featherweave coat worn with grey striped or puppy-tooth trousers is an excellent choice for Morning Wear occasions. This ensemble must include a waistcoat. This can be in traditional buff or grey, or for a flourish of colour, is wonderful in a pastel shade such as duck egg blue, yellow or pink. Stick to linen or wool for this. A grey Morning coat with matching vest and trousers is an equally good option, but allows for less creativity.
Your morning trousers will require braces, and whilst they may be hidden under the waistcoat, do have some fun with their colour. Pocket squares are best in linen or batiste, and work in pastel or neutral tones, complimenting your shirt or vest. Your tie will help anchor your outfit, so give it due consideration.
