Thanks everyone for the sympathy and good wishes for my AWOL suitcase.
The suitcase arrived first thing the next morning, but thankfully not before I bought some fetching charcoal wool trousers and the sweetest little black ballet flats (little being a relative term of course, as all shoes in my size are in fact honkingly gigantic).
I rarely feel completely justified buying new shoes, so really it all worked out pretty well.
Much sock knitting was accomplished on the plane, but The Stinky Bitches and I are off to Martha's Vineyard for a fabulous weekend of cooking, knitting and relaxing.
Edited to add, it's possible I've overpacked.
Many more pictures and goodies on my return.
