YASMIN YAS SEWELL Vice president of style and creative at Farfetch

I think people would presume that power means a suit but, in my opinion, a great T-shirt or something very understated can make you feel just as confident. Quite often, if I have an important meeting or presentation, I think about what I need to wear to feel good. I might try on lots of fancy pieces but, in the end, I often go back to something that I feel super-comfortable in. With ease comes confidence. 
