consider two scenarios: interviewing the same person, who comes across fine, but is dressed too formal or too informal
right at the start of their employment, would you rather tell someone that in the interview they dressed too formal or too informal and they should sort it out for their first day? it’s the former over the latter, every single time.
therefore, wear a suit if in any doubt whatsoever
when interviewing someone for a creative job it’s gonna be pretty fucking obvious from talking to them if they’re a creative who hates the idea of suits but accepts them as needed in certain life situations or if they’re actually a corporate twat who genuinely thinks wearing a suit every day of the week is cool
