At first glance, Prince William does not show the same level of enthusiasm for style as his father. Prince Charles is an ardent supporter of British construction and the bravery of the Savile Row, and his wardrobe is a combination of impeccable sewing and worn pieces – some of which he continued to wear for more than four decades. Prince William does not have the same appetite for fashion, nor does he seem to be interested in high fashion brands (look at you, Harry). But for the last 20 years he has created a solid roster of clothes on which he relied. Speaking as someone preparing to look down the barrel of 40 himself, it is a period of life that a man adapts to his style. When should he know exactly what suits him and what exactly the fashion nonsense to leave behind. As the Duke of Cambridge grows older, he has come up with an appearance that suits his role and lifestyle – and others could learn from his approach.
