Zara Bomber Jacket

Hi, I bought this beautiful men bomber jacket size S from Zara, new collection (item # 4302/301) but accidentally threw the receipt in the garbage and since it is a little short to my boyfriend on the arms, we have to sell it. It was a Christmas gift, we tried to exchange the size at the Chinook store today but they wouldn’t let us without the receipt, even though I have the credit card transaction showing I had a purchase there just a couple weeks ago. I paid CAD 83.85 with taxes but will sell it for $60. Please let me know if you would like more information on it. Feel free to check Zara’s website for more information on material and size guide.
