In the fashion world, we often hear this question in some form: Can I wear brown with black? Can I wear shoes with no socks? Can I wear this with that?
There are many outfits that, even as men, we can put on and feel insecure about. This shouldn’t be one of them. When wearing some sort of polo with a suit or suit jacket, I prefer the material of the polo to be a softer, cotton-like material. A cotton pique polo is tougher to wear with a linen or cotton suit than that of a 100% cotton polo. So my advice here, is to wear a full on, cotton polo when going for the suit/polo shirt combo.
