I've heard that it's better to overdress rather than under-dress for professional interviews (ex. go with a blazer instead of a cardigan, heels instead of flats.) And, of course, you must remember to wear the most important part: a smile! :)
P.S.- I gave you an award! Check it out at my most recent post:http://thatshortblondegirl.blogspot.com/2011/04/award-giveaway.html
