Dress code for shadowing in radiology

I’m going to be shadowing a rad tech in a hospital for a few hours next week and don’t know what to wear. I haven’t started my radiology program yet, im just doing this as an initial job shadow to explore my interest in the field. Should I be wearing business casual (im a girl btw, so slacks, a blouse, dress shoes?), business professional, should I buy a pair of scrubs? They haven’t told me a dress code yet.
