Interview at an electric utility company; what to wear?

Hello,

I have an interview next week for an apprenticeship as an IK at an electricity supply company – I think you can guess where 😉

Now the question arises: what should I wear?
I was thinking of wearing dark blue suit trousers, a black leather belt, and black shoes. I'd like to wear a nice wool sweater on top. What do you think?

I still need to buy the shoes and the top, and I have about €70 available for that. Perhaps you have ideas for matching shoes that aren't over-the-top, but also not under-the-top 🙂
