Update - the interview was this afternoon and after all of your generous advice I remembered that I had a black "business bag" in my closet. It was large enough to hold an unfolded copy of my resume as well as my day to day items (so I only had this one bag). I had done some research on the company and found that their products have been featured in Glamour, Vogue, InStyle, etc. I actually commented to the CEO that I really liked one of the bags that I saw in Glamour and *surprise* he gave it to me.
Thank you all again for you great advice!!
