No problem Greenhill. It's also interesting for me to listen to customers, even if mine aren't really UK any more. 
There is a huge difference in profile between a UK customer and say a German one, who shops very traditionally and therefore drives a different retail range.
I think our volatile UK weather also has a lot to do with it. it's the same argument with salt on the roads, snow closing everything, and airport delays. The weather is so changeable and radical there aren't the resources to plan for all eventualities, in government, retail and many other aspects.
Incidentally I set up a "Never Out of stock" range when I took over this side of the company I'm on. We started with a clean sheet, listing all the basic product out customer feedback told us they'd want. Black, grey, white etc.
When we added up the styles we were x2 over budget! And there would have been no room in store to repeat best sellers, add seasonal colours etc. Who would really shop a store full of black and grey jersey? It would look hideous.
The problem is, one poster on here saying they want a basic long sleeve tee would imagine a very different basic log sleeve tee to another. Ribbed, jersey, lycra, round neck, boat neck, v neck, fitted, loose, thick, thin. If you onlyhave room for 4 styles of basic in that category how do you make each customer happy?
Anyhow we planned 50% of our "buy" on this NOOS range. Two years later I am selling about 10% of the original range. The performance just didn't earn a continuity place. Worst performing was the kids range of grey, black and navy sweatpants. Safe as hell, based on our best selling shape. We kept them all year round with a realistic sales plan (2 in every store, every week) and only managed to achieve 45% of that plan.
Our best selling kids product is a powder blue jogging suit at the moment.
