As a lot of men these days are working in corporate environments that are a lot more
laid back and much more easy going than they ever were before the demand for shirts that are a lot less stiff and starchy has risen in the past decade or so. A lot of men also now work in the tech industry in online startups and the like where the dressing rules are a whole lot more relaxed and in these environments men who would like to wear shirts with a bit more laid back feel had no alternative. T-shirts are great as casual wear but in many work environments no matter how relaxed they are, they are still a strict no no. The alternative was developed in the last few years and they are called casual shirts.
Casual shirts are shirts like you have never seen before and certainly have not ever seen your father or any of the older people in your family wearing before. They are shirts for a new generation of people and shirts for new situations and new environments and even new work cultures and jobs that did not even exist as little as twenty years ago.
A casual shirt is one that is still formal in style but in spirit is whole lot more trendy and stylish. A casual shirt is one that can be worn to work and then at the end of the day you can go to a trendy club in your work clothes and not stick out like a sore thumb.
Casual and stylish shirts are the invention of a number of new brands that wanted to reinvent the staid and boring shirt as a piece of clothing that was relevant for a new generation that lived and worked in a manner that was very different from our fathers. These shirts were made to be relevant to the young and hip men of today. Just like normal shirts they can be worn on their own for best effect or can be worn as part of a layered ensemble under something equally cool and trendy like a sports jacket for best effect.
These new shirts are also cut differently from normal shirts and they show off the male form to best effect and if you are someone who likes to work out and stay in shape, you will look like a million bucks in one of these shirts.
