Playing devil's advocate here - what are your favorite fashion apps?
Jo: I just bought my wedding dress on Net-a-Porter an hour after I got engaged on top of a mountain so that wins right now.
Lucy: I love fitness apps like Flybarre and Nike. I adore American Vogue Instagram and the Elle.com web site. When it comes to clothes and shoe shopping I still like to try things on.
