In January I have spent £462 on a Gerard Darel dress and trousers, APC jumper, wool scarf at TKMaxx, Woolovers black jumper, sweater, shirt and silk blouse from Aubin and Wills, cowl neck animal print top from Micheal Michael Kors, denim shirt and breton top from oasis. Apart from the oasis stuff everything was in the sales and I have just worked out that my average discount was 56% 
I went back and had a look at this thread from last July on the same topic and at that point I had spent a similar sum for the first 6 months of last year. For that I had bought 17 items, mostly a lot cheaper and of the 17, 2 have already been binned
and 7 more are likely to go by the time I finish my current wardrobe sort out mission. The January shopping was based on a list I have done of wardrobe gaps and it will be interesting to see in 6 months time if my 'retain' rate has improved.
Of the 17 from last July, 4 are now staples, a Peony and Moore bag, Hobbs top and skirt and Zara scarf which seems to mostly support the theory of 'buy less and buy well'.
For the rest of this year I am giving myself a budget of £100 per month.
