You must pay the shipping cost for returns to CHINA! I purchased a pair of fleece lined tights as a Christmas present, then they made me submit photos of the item, then they told me, 'you should give the item to a friend. The shipping cost is very high and it will take us a long time to process your refund'. In other words, tough luck buddy. They pretend to have a return policy that makes sense, but the reality is that the shipping to China is more than the value of most items you will purchase here. USPS cheapest way is $35, UPS, and FEDEX even more. They don't have a state side consolidator to lump their returns and lower your cost. GOOD LUCK - I hope it fits.
