I purchased this along with a pair of pants, but I never wore it and it's been stored in my closet. I bought it when the brand wasn't very well-known, so it doesn't have the square product tag. However, I have something in the fourth picture that proves its authenticity, and I can include it if you need it. Please take a look at my past listings to see that I only sell authentic items. I'll be happy to answer any questions about the size, etc., so please feel free to comment.
