I'm sure you've all seen the new christmas advertising campaign for Topshop.
It's causing quite the stir across the social media and blogosphere!
A very clever way to spread the brand across the globe...
The main culprits as a guess for 'who's that girl?' are these lovely ladies!
Olivia is Chloe Greens guess... same hair! but is she engaged?
This is the biggest guess from everyone! Here's hoping!
There have been a few rumours (she's american, she's english, she's an A-lister) but from the pictures I think you can tell that she's young, fashionable and engaged, my guess is as good as anyone else's!
So, who's that girl?
We will have to wait and see!
