Thanks for all the lovely responses. Suz - a half day might be a bit hard to manage, - but I could do a "Shiny" and check out one shop thoroughly in one lunchbreak. There are actually lots of high end shops near where I work that I have not been game enough to enter (yet!)
Elly - you are right - Sveta is a similar build to me. I have some similarities with Mo and Suz too, (we are all around the same height).
I wanted to say that while I am in a SYC stage at the moment, that I have bought a reasonable amount in the last year and am pretty happy with what I have. Sure, that blue colour block dress isn't quite so thrilling when I have worn it every single week ! - but I think I am in that stage of wardrobe development where I can quickly and easily pull out an outfit and it will be a flattering colour, fit and if not at the cutting edge, not out of date. And then I can just forget about it for the rest of the day.
