In short
A morning suit is traditionally a black or grey morning coat with a peak lapel, grey striped trousers and a waistcoat. The coat should be cut close to the body and finish at the crease of the knee; the trousers sit high on the waist with a small break.
Summer brings the events that call for morning dress: weddings, Royal Ascot and other formal daytime occasions. It is one of the few outfits whose design has barely changed.
The coat
Traditionally a black coat with grey striped trousers and a waistcoat, though grey and blue coats in plain or herringbone cloth are now common. The coat contours close to the body, nips in at the waist and drapes over the seat. The lapel is always a peak, which draws the eye from the shoulder to the waist, and the length finishes at the crease of the knee.
The trousers
They sit fairly high on the waist, which is against most modern instincts — but morning dress is a nod to tradition and some rules are worth keeping. The leg should fall as a straight line with a small break just above the shoe, never pooling at the ankle. Houndstooth is a good option if you want a change from a stripe.
The waistcoat and the details
Usually double breasted, though it need not be. Pastel lavender, pale blue and beige are traditional; velvet and stronger contrasts are used too. Cufflinks or a pocket watch and chain add personality. If you are wearing a boutonnière, leave the pocket square out.
