Help!! Got a black tie do next week and am going for the butch look with killer heels. Got the top half - a plain black, structured top with gold buttons on cuffs. Now I've got three hours left in which to acquire trousers. Trouser wise I need size 16/18, slim legged, and nothing too hot or itchy that's going to turn me into a sweaty blob. Bonus ball would be some kind of poncy piping down the outside leg (gold? black?) but frankly I'd settle for anything nice that fits and looks relatively posh. I'm in London for work and spent three precious hours today in Oxford Street weeping in changing rooms in Frasers, Lewis's and, in desperation, Selfridges. I have tried on the entire stock of Hush, Boden, Linea etc - nothing is working. I have three more hours in central London tomorrow and if I don't find anything, I'm fecked. Help. Where do I go? (Also looking for gold oversized clutch and green/gold/bright heels but can do them on the weekend if necessary - the trousers are the priority).
