Slowly to some parts, I think. St James' Street is lagging behind a bit although Berry Brothers have come up with a couple of beautiful wreaths to decorate their windows and Truefitt, my favourite grooming parlour (for men that is!) look very dapper with their display.
Jermyn Street looks great - at night these overhead lights look magnificent.
And, the entrance to the Piccadilly arcade looks lovely with the purple and orange display.
But, for me, Mayfair wins hands down. It has a far more Christmas-y feel to it particularly around the Mount Street/St Audley Street area. George's members club has really gone to down and looks gorgeous:
It's a little bit like entering a grotto! And Mount Street Deli have also pushed the boat out with their Christmas look.
The aerial display in Mount Street is also very sophisticated - just what you would expect from a neighbourhood with weekly rentals exceeding £4000!!
