What's your armour? Viv Groskop talks to Jane Shepherdson, chair of My Wardrobe HQ, former chief exec of Whistles and brand director at TopShop. They discuss the way clothes can make you feel powerful- and how "rent-a-porter" can rekindle a fashion love affair without sacrificing the planet (or costing the earth). Jane reveals how she found her purpose and reinvented her career. And she explains how to deal with difficult characters, why you must surround yourself with excellence and how to get paid what you deserve.  Find out more about Jane's latest venture at mywardrobehq.com Viv's latest book, Lift As You Climb is out now. @vivgroskop
