A single breasted blazer is the most versatile tailored jacket format. One row of buttons means the line is clean and uninterrupted which keeps the look more modern than double breasted. Single breasted jackets also tend to work better on a wider range of body types because there is less visual weight at the center front. The jacket can be worn open or closed which gives you styling options depending on what you are wearing underneath. A single breasted tailored blazer in a neutral color becomes the uniform of anyone who needs to look put together. The fit needs to be precise through the shoulders and waist because single breasted styles do not have pattern to hide fit issues. These are the single breasted blazers that work because they are genuinely practical.
