Interview in management

Tomorrow I have an interview for a management position working with people whom have disabilities. I’m already in this field of work as an independent contractor cna and caregiver. I’m going to have to show up in my work scrubs due to the fact I commute an hour to where I work and I’ll be closer to where my interview is at and I work NOC. Is this okay or unacceptable? Also if I take a copy of my resume would it look better if it’s in a folder or some type of sheet?
