Double Breasted, It's All About Fit...

Double Breasted blazers can be especially tricky to pull off. If it is too big it'll only make you only boxy and bigger than you really are, if it's too tight well simply it looks like it is too small for you. As a bigger guy wearing any blazer that is too big can only make you look that you are 10 pounds heavier than you really are. Even as a smaller guy, a blazer that is too big on you will make you look bigger than you really are. Fit is extremely important in making you look the size you are and making you look your very best.

Below are a couple examples of before and after of the Banana Republic Double Breasted blazer I picked up a few months back. You'll see how there is pulling in the before pictures and how the blazer sits better once the button stance was moved. You'll notice how it is just a bit too long in the before pictures and how much better it looks after it was shortened.

Before:

Notice the X created which is an indicator that it's too small. The jacket also goes well beyond the mid-thigh.

After:

Notice the X is much smaller if barely there as the pulling is due more to the arm being held up to take the picture. The shorter length is also much more flattering.
