Well I agree with everyone else, it does depend on the industry. I work in a creative field too so now only rarely wear a suit for work (the odd important meeting does require it, as would court reporting if I ever did that....which I don't). But, I think the role you're going for within your industry does matter too. I wore completely different outfits for two job interviews in the last year - one was for a creative role in a department which sees itself as very creative so I went for my own style but a particularly good version of it - a slightly unusual blouse, layered under a dress, with heels and a great jacket. I would have been worried that a suit gave an uncreative impression. For another job, which involved managing people and for which I spent the whole interview being quizzed about "leadership", I very emphatically did wear a suit - with a vintage shirt and wedge sandals to avoid looking like someone else entirely. It sounds as if the job you're going for is more senior - so perhaps a suit wouldn't be a bad idea? I came second for both jobs, FWIW. Make of this what you will
