I have a size small body and size XL arms, so when I got this jacket for Christmas:

It fits perfectly through the torso but the sleeves are at least half an inch too short. Does this look like it could be stretched or altered? All that is left is a large and that will surely be way too big on me without adding much sleeve length. I am concerned about the zipper at the sleeve, as I think I may make the job more complicated.

So...return or alter?

Oh yes, and Merry Christmas to those who celebrate!
