I love a red coat, I love a red double-decker bus, I love how her facial expression seems to say, "I can't see anything past each long hank of hair in my face and it is taking all my power to just levitate my hands here and not put it up in a ponytail right now."
It's rather entertaining to watch said center-parted (or, I guess because she's English, centre-parted) hair slowly migrate first behind one ear....
...and then both. The better to see the men in uniform, after all.
