I’m far from cover-of-GQ but I did wear a suit every day for a few years to a programming job. Maybe it’s the punk in me but when every person in the company, including the C suite, dressed in a t-shirt and jeans or sweats I felt the need to be a little counter culture. Honestly it was an insightful experiment in biases, seeing how different people treated me (such as your admission) based on my clothes alone. … and I have no trouble writing fizz buzz.
