Sienna Miller is rapidly becoming one of my favourite fashionistas – on and off the red carpet and this is an example of why! She was pure perfection on the red carpet for the premiere of the The Lost City of Z. Her dress was by Alexander McQueen and combined boho and boudoir elements; the result was romantic and sweet without being saccharine. A braided hair do and metallic sandals completed her pretty look. Do you love it as much as I do?
