For posh London nanny positions. I'm thinking the whole 'black trousers white shirt' thing. However I'm yet to find black trousers that don't attract every tiny stray hair and fibre so you end up looking like they're made of mohair! The shirt also needs to not be see-through, and somehow make me look as if I have boobs (I'm pretty much flat chested!) and yet magically streamline my size 14 tummy... Any recommendations? I'd like good quality, and could spend up to about £150 on the whole outfit.
