I used to do that when I was ceo of a company. I had a blue jeans and white button down shirt uniform, but, I didn't even know it - I was just so focused on the products. I must of had 20 of each. One day we had a company meeting and everyone came to the meeting in my uniform. It was hilarious and awesome. And that's when I found out.
"IBM officials often tried to accomodate Apple and vice versa so that both could comfortably work in unison. One popular anecdote talks of one of the first meetings between the two computer giants. IBM engineers dressed in blue jeans for the meeting, while Apple engineers dressed in suits. They both tried to make each other feel compfortable by conforming to what they thought the other was like."
