Kicking off the 2013 US Open Tennis Championships was the Arthur Ashe Kids Day, hosted by the FLOTUS Michelle Obama as it is part of her programme to get kids active. For the occasion Mrs O had a style triumph in this amazing yellow Prabal Gurung peplum top that she paired with white trousers and some comfy trainers.

I think that this is just about the most perfect outfit she could have worn. And I really wish I had it in my wardrobe. It is casual, but eye catching and elegant. It is age and event appropriate. And it is super fashionable. Winning all round. Well played, again, Mrs O.
