Sienna looks terrible, I actually didn't recognise her in the photo on the right, I thought it was an aging Kate Moss or something. The glasses aren't too bad close up though, but I just hate grey and black stripes, they look way too cheap.
Kiera's outfit is low budget, her Luella-esque top's from Top Shop, but she's wearing florals!! And ankle booties that aren't scary like Sienna's are! And a Pencil Skirt! I would think wearing a pencil skit would be a little too conservative, especially since the Luella blouses were paired with high-waisted minis, but Kiera pulls it off so well. And I love her crooked toothy smile.
Wearing a jumpsuit here, while Sienna wears a flappy fringed dress Kiera wins again but I like how they coordinated their outfits. (justjared)
