When I first started working, ties in the office but not working on-(work)-site. After grad school, suits were pretty common in product management/marketing/etc. and ties at least pretty common in general.
When I came in to talk to some people I mostly knew for my last job ~15 years ago, I did wear a tie and jacket and a couple people joked a bit but I knew them and they had been around long enough to know I just wasn't taking anything for granted.
I remember once showing up to the office after taking the morning off and one of my co-workers asked why I was wearing a suit and I told him I had a job interview. He thought I was joking and later repeated this to someone else and then said that I had fooled him with that before.
Except I did have a job interview and I was so glad to be out of that workplace.
