Let's start with the jacket or blazer. I go for a fairly classical shape (not too short or long, conventional-shape lapels etc) and wear it for all occasions, formal or not. Coming in a wide variety of styles and materials, it can be the most versatile and useful item in the wardrobe. Make sure it fits well, particularly across the shoulders; avoid a baggy fit and over-long sleeves.
