As you can see, the Primark flagship store in Marble Arch is a whopper: they have a whole lot of windows to fill!! I was actually impressed, especially given that they are such a budget store, by how much effort they had put into their windows. I really like the styling too: very young and trendy and perfect for their target audience.
Also worth noting are the facing of some of the people caught in the pictures: they look like they've been sat waiting for days don't they? That should give some indication of just how big the store is: you can lose whole hours in there without even noticing!!
Have a great Sunday!
