Rather than thinking about the suit itself, I’d consider the dress code or culture of the company you’re interviewing for.

Turning up in formal business wear isn’t going to be a positive social cue if everybody you interact with is dressed casually.

The social cue you’d be giving off is that you stick out like a sore thumb and probably didn’t do your research on the company before you showed up.

Literally no different than turning up to Lloyd’s of London in a Hawaiian shirt and Bermuda shorts.
