as both a stylist and a fashion editor you will need a portfolio of shots/ tearsheets. essentially, both positions are stylists. a 'stylist' is either a freelance stylist for different publications, or a more junior person in the fashion team on a magazine or other publication. a fashion editor has been a stylist and has enough experience and fashion business know-how that they can judge what brands to use to help the magazine, and can judge picking photographers and liasing for upcoming shoots with the editor. in some cases fashion editors can also come from being 'market editors' and others with a PR background. this experience helps them with the clothes/ advertising/ magazine relationships.
hope this helps!
