Most RTW sleeves are 17" in length and if you shorten by 3" you would have a length of 14" which is very, very uncommon to have such a short sleeve length. My hunch is 3" is more than you need to shorten the sleeve. The issue you run into when you cut the sleeve from the top is the sleeve gets more narrow as you move down the sleeve and you lose width on the top sleeve and it reduces the amount of fullness to baste into the sleeves resulting in a misfit of the sleeve into the armholes. If the top sleeve is too narrow it could create divots and tension in the upper sleeve. Take it to a tailor who knows how to fit/cut sleeves and see what he says. Regardless of what you will find out from this thread you need someone who can actually do the work.
