All Black Outfit Ideas?

I’m graduating soon and my graduation dress code calls for an all black semi formal/formal outfit. I want to wear a formal attire but also have a sort of personality to it, basically wearing a formal outfit not for the sake of wearing a formal outfit but a fashionable reason I already have some Armani trousers I got from eBay and I was thinking of getting some sharp looking shaped shoes with a shine to it for a nice contrast to the rectangular body shape I have with it tucked in. Solovair Gibson shoes maybe? As for the top, that’s where I need some suggestions for, maybe a wool sweater or smthn? I mean I could always go with a black dress shirt but idk
