I thought this might be about people that mostly only use clothes they got as swag. Like me. I am a walking billboard for companies of which only a few I know what they do.
Puppet (the server software) seemed to go hard on this and I think I ended up with 5-6 shirts even through we never rolled it out into production. I mostly wear em to the gym or use em for sleeping.
I try very hard to to wear any clothes with logos. For some technical clothes it can't really be avoided, so much of my winter/snowboarding/climbing/other sporting gear has logos, sadly.
