My wife bought this for me as a present. It isn't authentic in its cut, but I had been scouring the Lounge and manufacturer websites for a while and she had seen it and went with the LL Bean Flying Tiger. I have read reviews etc, but a reason she went with this was an open-ended return policy and shipping both ways in case it didn't work out. Not sure exactly how slim/tight to the body this is supposed to be. The hat is vintage BTW. Thanks.
