i carried a purse and black leather portfolio as well. the portfolio came in handy when at the interview day, they also gave u additional folders or papers and i can just put them all inside the portfolio when i leave or move around. at my last interview, i asked for the interviewers' info and the student interview didn't have a card, so i let her conveniently write down her email in the paper notepad which was part of the portfolio. but for my other interviews, my portfolio wasn't much of a use except carrying school infomation papers, but i find being prepared and ready for any given situation is good. i see many girls carry purse and others with portfolios so it depends on girls. at western u's interview day, we were given free time to talk, eat stuff, go to bathroom, when we were waiting around for our interview or for others to finish interview so you can go to the bathroom and do any touchups or make sure you look your best before you go to your interview.
