Well, I found an Argyle jacket on ebay that was a 42 and I'm a 42 but it would probably fit a 40 better. On the other hand, I then ordered an Argyle and vest from J. Higgins and it's a 42 and fits very nicely. I've always heard that if you're ordering from the UK, go a size up...I'm not sure how J. Higgins reconciles that...if their stuff is made here or what...but that was my experience.

And I have to remember to put that original 42 back out on ebay one of these days...

Best
