Maha wear what you are comfortable in – it’s what you are going to say that will be most important, that’s what we’ll all remember. I have to confess to having similar anxieties- and I think some men do too. Remind me to tell you about my colleagues son’s hunt for the perfect pair of trousers for his wedding! I always wear shoes that make me smile, that way if I look down and see them when I look up again I will be smiling.
