I work in an enterprise and have loads of meeting with folks that are wearing suits while I am in the technical side of the house. I could clearly see that the approach changed when I started wearing suit pants (trousers?) and well ironed shirt and oxford into the meetings than my usual tshirt and jeans.

As someone else said in the thread, it works like a shield and also a projection of authority somehow in those meetings.

When I realised that I started building my closet up with shirts and trousers and retiring my tshirts and jeans for work outfit.
