I'm flying to London next week for my first job interview in about 14 years! What do I wear?! I've forgotten. It's a creative job for a potentially stuffy department. Are trousers OK or should I play safe with a skirt ?
Main dilemma is what to pack. I am spending a few extra days there as a holiday - meeting friends and SHOPPING and I want to have a near empty case on the way over because I intend to fill it up before returning home. 
I need: clothes for interview, clothes for shopping and clothes for evenings out. Preferably all mix and match - which is good as most of my wardrobe is like this. Please help me see the wood for the trees and not overpack! Oh, I'm staying for 4 days, 3 nights.
Finally - what shall I treat myself to while I'm there? I deserve a treat but don't really need any more clothes. What accessories are de rigeur right now?
Oh, and finally finally - any recommendations for where I can get a good facial in central London?
