One of our members recently ordered and received a BR in a size 42. He has a 42" chest and wanted room for a sweater. Well, he got plenty of room. The alleged size 42 measured 24" p2p. That is equivalent to a size 46--way too big. He ordered the size 42 after talking with the customer service rep and giving him his height, weight, and chest measurement.
Interestingly, he requested the p2p from the seller, History Preservation Society, and was told the size 42 had a p2p of 23". Even with that p2p, that would be an actual size 44.
The p2p he was given for the size 40 was 22", which would be equivalent to an actual size 42.
So, the lessons we get from this are that the BR are sized very large, and we can't depend on the measurements given by the Historical Preservation Society or the recommendations of the customer service rep. The BR is a nice peacoat, however. But it isn't sized the same as the WWII coats or even the vintage or current issue coats.
The company does offer free shipping both ways in the event of a non fit, so he isn't out any money because of this.
When he gets another size in the BR, I will post the p2p for those of you who might be interested.
Thanks for your post for those interested in buying one in the near future!
