I got a Goatskin Raiders & it's a truely beautiful jacket. So well made 
However...
I do have one small issue & I'm now so confused about what to do, I really need the imput of the members here
Basically the seam across the back...well when I put my arms forward in any way I can feel the seam putting pressure right across my back. Now whilst it is not painful, it is anoying & quite honestly, worrying about it is ruining my enjoyment of what is an otherwise perfect jacket in every way.
Now I'm 5 foot 8 inches short & I'll be the first to admit I'm carrying about 2 stone in weight more than I should
Mostly on my torso & tum. That said, I tried on a 40 inch chest jacket & Peter himself (great guy - I'll get to that in a moment though) measured me for arm & jacket length which obviously fit perfectly 
Unfortunately I didn't really test with the size 40 I had on the amount of fit I had round the body/mobility of my arms.I asked Peter for the chest to be a 41 to give me a little more room & my jacket does have plenty of chest room, even with the action pleats pulled in fully. I also have double 'Jagger Lips' under arm gussets. It's just when I put my arms forward, even for something simple like holding a magazine, that I can feel the seam across my back & wonder if I've got enough room there
So the questions are...
Is this normal? Has anyone else had this with their jackets? Am I worrying about nothing?
Do I need a bigger jacket? (I did speak to Gerry/Jerry at Wested who said that going up a size would only give me an extra 1/2 inch on the seam total. Anything bigger for my size would have the actions pleats open all the time & looking as he put it "... sticking out like wing nuts"!
)The seam on my jacket meets with the seams running up the back of the arms, which is the current standard on Wested Indy jackets; but studying Raiders, the original jacket on screen has a seam about 1.5 inches higher that the arm seams from my estimation.
So would raising the seam work better?
Does anyone have an older Wested jacket with a higher back seam, or had one made that way? (didn't Got Maul have his seam raised?)
Wested seemed to think it would not help & said that they had dropped the seam down to again stop the action pleats staying open.
So please, anyone who can speak with experience, knowledge or authority on this subject, chip in (Michaelson ???). I'm pretty desperate to get this sort
(Let me just making this clear, I have absolutely no critisim of Wested. They have been nothing but helpful. This issue is either a problem of my own mind worrying about nothing, or I need to get a truely fitted jacket made to accommodate my particular back (no I'm not from Notre Dame!))
BTW, as I was saying, Peter, what a great guy
We had a chat about the UK Summit & a few other things. I got the impression from him, he really does enjoy meeting up with all the gearheads & has a genuine affection for us mad people 
Very, very cool 
) when I notice it the most while I do not when wearing my FS lambskin (contrary to Bufflehead's experience with his "real close fit" Wested lambskin raiders) where the leather, and thus the seams are more supple. I've also experienced it under the arms with my goatskin on occasion. And I can assure you that as the leather around those seams itself eventually relaxes after months of heavy wear (becoming desirably more supple, more so than the seams themselves will ever be) you MAY notice it even more with the seams in essence being the 'wire' framework which holds the jacket together ...which should be a reassuring feeling as long as you say it's a feeling of "pressure" and not a feeling of cutting into your back. It seems quite normal to me considering this type of hide. IMHO, it is nothing to be concerned about especially considering you were fortunate to have Peter fit your jacket himself and getting the other corroborative information you did from others at Wested. After awhile you will get used to the annoyance you describe. I also agree that going any larger will not look good in regards to the action pleats on a stiffer goatskin, nor will any attempts to raise of lower the seam running along the back lessen the "annoyance" you describe without risking the 'look' of the jacket unless you're willing to live with raising the back seam an extra 1.5 inches higher which may or may not help.
Since you're fortunate enough to have direct access to Wested's shop perhaps you could bring this up with Peter? Maybe we could get this change incorporated into the design? Fan input has been used in the past, so maybe we could get lucky.
) or "hug myself," I too feel the tight pulling across my back and arm-pits even if I order my correct jacket size. When I wanted to order a Flightsuits Goatskin Indy jacket before last Christmas, I ordered my correct jacket size (thinking that the Flightsuits runs a tad larger than the Wested fitting). But when it arrived, I felt that it was quite the opposite. To me, personally, it felt as if the Flightsuits was a tad "smaller" in fitting than the Wested that I owned (even in the exact same size
