I read on a previous thread that we should conclude our threads, so here goes....
I didn't do very well at sticking to only 2 or 3 things, the first shop I came to was Benetton (which I haven't been in for years) and bought.. long sheer v. pale grey cardigan, 3 lovely vest tops in white and a greyish colour which will be perfect for layering and a flowering scarf in khaki with shades of blue and coral colours.
Went to C de C, as advised, but after trying on lots of blazers (all in the sale) couldn't find the perfect one and already have a BR petite trench.
Then went to Reiss and tried on lots but only came away with these trousers think I will get lots of wear from them, can wear in the day with ballet flats or high heels in the evening. On me they are 7/8ths, I assumed this was the correct length 
Hobbs - to spend £25 voucher, found a summer denim skirt which was the perfect length, right on my knees.
4 smart t-shirt tops from M&S (with CC vouchers) - 2 with utility buttons on shoulders with pocket, one vest with exposed zip up back and one long sleeved navy.
Then to Oasis to change a present, bought tan skinny belt and two pairs (navy & khaki) of reduced houlihan rip-offs, that I really love. They are much better than the uniqlo and Gap versions as they are proper skinnies.
All in all, £285 so DH was pleased. Obviously bought pressies for DS1 still stuck at home with chicken pox.
I was pretty hopeless about only buying a couple of items but everything is interchangeable and I have good shoes / boots to match.
