This is an important thing to consider with whatever you're buying, but shoes especially. We make some of the best shoes in the world in England, so 'Made in England' is something worth paying extra for with a good pair of shoes. Spend £200-£300 on a good pair and with care, there's no reason why they shouldn't last for 10 years.

I bought a really nice suit from Burberry recently, but I paid a little more for it because after looking at some Paul Smith suits 'Made in Portugal' and various other brands made around the world, this particular Burberry line was 'Made in Italy' and the quality of the cut and manufacture was visibly superior.
