I found this beautiful navy santana knit sweater in a thrift store for a dollar and had to buy it. It looks and feels to be of St. John Santana Knit quality, I am just a little weary because I have never seen this label before. Also, the size says size 44, aren't these usually always US sizes?? So I am wondering if this is vintage St. John or a very good imitation. I didn't see the label on the label resource page, so I though someone might have some info for me or at least point me in the right direction. Please help!! Thanks!!
