Carey Mulligan in The Row, Isabel Marant and Salvatore Ferregamo

This look may seem low key and casual, and that's just the way that Carey Mulligan likes it. But actually it is action packed full of the most fashion forward designers. Let's start with that jacket from the Olsen twins line The Row. Brushed silk tuxedo style in a deconstructed way. Perfect for dress-down business wear. And those jeans? They are only Isabel Marant, the casual wear designer of the moment. And if that wasn't enough, those cute little ballet pumps are from the newly energised luxury brand stalwart, Salvatore Ferregamo. That is quite a power punch of casual right there.

Of course much of the attention was distracted from this perfect power pairing but the fashion faux pas of having the label still stuck to the bottom of the shoe. I personally find it endearing - how many of us have done the same? But the fashion press were outraged. How do you feel about this slip up? Does it spoil the look for you? Let us know.
