A suit tells the world you are ready for business. A jacket tells the world you are open to fun. For me the ideal jacket should have soft and natural lines and balanced proportions. It should fit you but not constrict you.
I do not believe in stiff shoulder pads.
That is vanity, not style. Do not make it too tight. If it’s too tight, you will look like a matador. Any time I see a man playing golf or tennis in his jacket, I know he and I could be friends.
