Should Chemists 'Dress for Success?'

Chemists: Does your workplace have a dress code? Should it?

Long-time readers may remember that I opined on this very subject waaay back in the early days, noting that long-term bench work does a number on nice duds. Well, I've since switched jobs, and in my current role I'm often called upon to meet vendors, interact with inspectors, and strike up academic collaborations. So, jeans and beat-up T-shirts are decidedly out for me.

I've found that thrift stores (Goodwill, Salvation Army) tend to offer reasonably nice business casual clothes for 20-30% of the original items' costs. And, as Chemjobber has pointed out, proper lab PPE certainly helps to protect any investment you make on the sartorial front.

But out of sheer curiosity, I wonder: does anyone get to wear jeans and T-shirts past grad school?

Let me know in the comments. Thanks!
