How was Jane Seymours fashion different from Anne’s? Could you perhaps do an article about the fashion of that era?
Tudor costume is not my expertise but costumer Bess Chilver wrote an article for us on costume and fashion - see http://www.theanneboleynfiles.com/resources/tudor-life/tudor-clothes/
There's are also a couple of articles on Tudor fashion on one of my boards in Pinterest - http://pinterest.com/anneboleynfiles/tudor-fashion/
Jane Seymour favoured the English style Gable Hood and historian Maria Hayward, in her book "Dress at the Court of King Henry VIII", writes that "While Jane Seymour forbad her attendants to wear the French hood, no examples of the English hood (gable hood) survived in her wardrobe at her death, even though she had been painted wearing one." So, that's interesting! Catherine Howard preferred the French Hood because it was far more stylish.
