I received a size M instead of the size S I ordered, I filed a complaint but had to pay the shipping costs, which were €9, as they did not guarantee that they would refund that amount. I have disabled the return option since my sister-in-law is keeping the jersey, which fits her well. I recommend that the seller review the orders before shipping them, and if they need to be returned due to the seller's fault, I should not have to pay or advance the return shipping costs. I have rejected the return due to the aforementioned reasons.
On the other hand, I will say that even though the order doesn't work for me, the jersey is very nice and my sister-in-law is delighted with it.
