Essential item No 1. The striped shirt, long sleeve or short sleeve preferably with navy and a loose easy fit. Can be worn in winter with a navy coat or in summer for picnics by the lake or a seaside adventure.
Item No 2. The trouser. Chino's for summer in Navy or Beige and in winter perhaps some wool trousers but NOT in beige, good god man winter is not for light colours. Navy, Black or Brown will do. Now don't be distressed.
Item No 3. A nice comfy sweatshirt. Simplistic in style and not too tight, almost all colours will do...not outlandish colours though, grey, navy, black, maybe mix it up and get a forest green. If you don't know what to wear this with, then you might be beyond help. In fact...do you ever get dressed?
This is just a rough guide to what I think are the absolute essentials and suit every man on the planet, of course being a modern man you will need to invest in some good jeans (a dark blue) as well.
