The only way is not to shorten the hem
and thereby destroy every proportion on the jacket.
The only proper way
is to take the entire jacket apart and take-in the cloth at the top shoulder seams where the front and back panels join. This is ridiculously expensive and requires major panel and arm-hole re-cutting. Additionally, it is quite possible that the sleeves would require additional tapering, not merely shortening. Most decent tailors would charge you at least five or six hundred dollars to properly make these alterations.
Hypothetically, and no slight to HF, I wouldn't think their garments are worth the investment in such major alterations. The Oxxford, again hypothetically, might be a different story if your original cost was modest enough.
Most Soutwick suits are only partially canvassed. But if the eBay suit in question from your later post needs only sleeves shortened and the price is right for you, don't you think it's better all around?
