Yes. I never play fancy dress with suits. Formal for me means a nice, comfortable shirt and jeans or other clean trousers. On an average day I wear shorts and sandles because it's damn hot. I wear suits to funerals, and once to a wedding, but even most of the weddings I go to have a "smart casual" vibe them, no full suits required.

I rarely meet with investors or anything like that, but when I do, not dressing up is a test. If they judge me for what I wear, beyond basic cleanliness, we're not a good fit for working together.
