Corporate goth as a teacher

I might be starting a new job soon as a substitute teacher and if I get the job I will have to heavily adjust my wardrobe and I need a bit of help, my personal substyle leans very heavily into the more mallrat nu metal type of goth but definitely not suitable for teaching. I'm looking at more vampy outfits for inspiration but there isn't that much out there for corp goth as a guy, this might sound a little bit strange but I'm also trying to lean less in the direction of somewhat flashy clothes or too many accessories for the sole reason of middle schoolers being incredibly homophobic lol, silk button downs and dress pants absolutely work but I want to spice it up slightly so is anyone else a guy or masc presenting person in general and has to work a job with a rather strict dress code like I'd have to that can offer any advice? Appreciate the help in advance
