A bit hit and miss here, but I had some success today - a Nicole Farhi real wool jumper dress (looks, smells and feels brand new) for £8 and some M&S Autograph shoes (brand new) for £7. The jumper will probably form a wardrobe staple and the shoes will do me for weddings/parties.
There is also lots of complete tat and stupid prices in our charity shops - like stuff from Primark which has obviously been worn loads on sale for the same as it would cost new......
