I have seen a huge increase in Karen Millen (specifically dresses) being sold from China. While these look like a bargain, please beware that they really might not be. There is a huge issue with counterfeit dresses being made from inferior materials in Chinese factories - many styles of which were never even commissioned to be made there! (Ie - the black and white bow dress from last season, which was actually made in Lithuania!) These dresses are of a far inferior quality to the genuine dresses.
There was recently a buyer who bought a 2006 pink butterfly dress from China (the one made famous by Leona Lewis on X-Factor) that looked terrible when she received it - incredibly thin lining, and faded colours. You have to ask yourself why ebay would suddenly be flooded with lots of dress that were made 2 years ago in perfect new with tags condition. Especially when those dresses have been unavailable for purchase since then! While Karen Millen items are admittedly expensive, do you really want to go for the cheaper Chinese sellers knowing that there is a risk of additional payments (a good £30 sometimes) and after all that ending up with a fake that's worth pennies, or would you rather pay the British sellers a bit more and know that your item is 100% authentic and going to reach you with 3 days?
My fellow seller (and Karen Millen fanatic!) BabyHarry has an excellent guide on how a genuine from a counterfeit Karen Millen dress which can be found here:
