Secondary Headshot Outfit Question

Hi all! I was wondering whether a photo of me in a nice sweater in front of a white brick wall would work okay for secondaries (not comfortable posting a photo of me in public). I'm a girl if that matters. The health program committee said that it would work fine, but I've seen a lot of people talking about wearing full suits/blazers and wondered if I needed to do the same... thanks!
