I only wear a 'flying suit' if I'm flying something either oily, or where I need lotsa pockets, which normally means something old or military. However, even if I am flying something looking like the airborne equivalent of a Bentley, I DO wear clothing that is made of 100% cotton. And I always wear flying gloves, even in a Cessna.
Makes me cringe when I see pilots wearing polyester fleeces and plastic trainers to fly in
