I've been browsing eBay lately for the first time in ages, and amidst the dross I've bought some fab Boden pony-skin flats (£14) and two Pepperberry dresses for £3 each, brand new and unworn, to wear at work (Teacher).
The super well known brands don't seem to have many bargains, but I've seen some lovely bits from NW3 and Farhi - are there any other brands you'd recommend searching for?
