Alright so this is probably a look that none of us could ever pull off in our lifetimes. But we had to mention it because something about it makes Keira look mysterious... and hot!

Even if we couldn't pull this look together, we can still get inspired by KK's look and pick up a strapless cobalt dress and add a little tulle to the bottom. Nah, we'll just leave this Alexis Mabille look to the pro!

• Alexis Mabille dress, Sorry kids, this one is only available across the pond.

• Moschino pumps, Piperlime, $490
