How to find job attire for job prospect

I’m currently looking around for a job and found an inventory control supervisor position. I plan to apply, however, I’m not sure how to dress for the interview if I do get called to go to it. When I was working in inventory control, my supervisor wore some nicer jeans with a polo and some nice boots. Seeing this would be a position in the warehouse, would I be fine in dressing in nice jeans and a polo for the interview? Or would slacks and a polo be better? I planned on getting in touch with someone from said business (LinkedIn) to see if I can gain some insight on how management is dressed in the warehouse
