If that's the spirit in which you want to take this conversation then, yes, absolutely, show up to a job interview in a tux. If you're applying any where other than Downton Abbey, then you get what you deserve for taking the conversation in this direction
Can you help me get on track by sharing what you mean by its never a faux pas to show up overdressed? That’s the part that just seems quite surprising to me in my experience. I would say it’s just as easy to show up over as under dressed in an awkward way, rather than something that can never happen.
Ah ok, I had somehow misread your comment as saying it is never a faux pas to show up over dressed. Thanks for the clarification, that makes way more sense!
