messenger bags style

The thing about the Messenger bag style is that whether you are a traditionally masculine man or you are an artsy type, there is something for all styles.

Consider the following:

A messenger bag style should complement the rest of your look.

A messenger bag style should be such that suit the environment in which it will be used.

A messenger bag style should be such that suits your height and build. If you have big men carry small bags, it might look like clutches on them; but if small men or slightly small carry big bags they will have the same comic effect on the other end of the spectrum!

You can quickly use a mirror and check out your whole look and see how it suits you.

The purpose is everything! Consider the purpose of the bag. What do you want to use the messenger bag for?

Heavy Items: You can go for a durable bag that has a thicker strap with some padding on it.
