If you stated on ur auction that it is sheer, you shouldnt have to refund her ANYTHING, she should assume all responsibility, if she opens a dispute, she cant win. You STATED that it was sheer. This reminds me of this buyer that wanted me to refund a burberry bag i sold, I wrote down the dimensions and stated clearly there ARE no refunds unless its not an authentic item. She complained that it was too small and would settle if I refund her 50 dollars or else, she wants me to pay HER to ship the bag back to me... and i refused... sge opened a dispute and lost :]
