Linen vs Cotton: What makes the best summer shirt?

We've probably all been there: A wedding in summer, a company get-together, a hot summer day outside an airconed office or inside a non-airconed office.  Usually we dress in a cotton suit, or a little more casual in jeans or chinos and a cotton shirt - if we're lucky we can wear a cotton t-shirt or a cotton polo. We all know the stains by our armpits or collars and the shirt sticking to our body from the sweat. Nowadays about a third of all clothing is made of cotton and the majority of the remainder from polyester. Mostly, because it's cheap. Fast-fashion has boosted the use of cheap materials at the expense of mother nature. So our choice based on the two most popular fabrics is mainly between cotton and polyester - and sweating in polyesterwell.   So the question is:   Is cotton the best fabric to wear in summer?
