Just when I thought I was over lace, Sienna wears it fresh. Not only is this outfit a wonderful example of styling prowess — from the mismatching, to the layers, to the silhouettes — but it makes lacy layers look ever so lovely. If you keep the color story similar, a lace tank can add a flirty touch to a look. Sienna's is cropped, showing off her saucy leopard print Topshop pants. You too can achieve this look, just DIY crop your lacy layer. If there were ever a time to encourage experimentation, this is it.
