I think this is Sienna Miller but because of the sunglasses I can't really see but well. I really really love this outfit! It's perfect for summer on a hot summery day and for spring when it's a little bit colder with a legging beneath. She totally understand how to mix and match everything. I love the red coloured bag with the whole outfit and the red necklace. The shoes are also something really nice, it makes the look a lot less girly. The round sunglasses make it a little more weird but I totally love that! What do you think about this outfit?
