Mens Unstructured Blazer

Unstructured blazers are jackets that are made without the traditional shapes that we are familiar with. They are made in fact to be as shapeless as possible. Aside from the fact that these blazers tend to be lighter, since they are usually made of thinner fabric, the other appeal is style. If a casual style is what you are after, then an unstructured blazer may be the way to go.
