I've been asked to give a presentation at a conference next month and am worrying about what to wear! My favourite green boucle skirt which I wear with a cream silk blouse is now 10 years old and isn't doing what I'd like for my little pouchy mum tum. Any suggestions for formal conference type wear which will make me feel good and smart and not like one of the waiting staff at the drinks reception in the evening? I'm 5ft 4 and a size 10 but quite self consious of my tummy, particularly around my team who are all a decade younger and super fit!
