Cameron Diaz looks great at the premiere of her new movie Knight and Day. Because really, you can’t go wrong with a little black dress, a belt cinching the waist, and red lipstick. I love that she always goes light on the makeup but has some colour to pack a punch. It’s either going to be the lipstick or a liner, or the colour of the dress itself, but this is a style note that we can all learn from. The messy bun is just cherry on the sunday – because when you’re going with so many classics (black dress, red lip) you want to add some fun to the mix as well.
