Are you planning to play a Zombie role in Walkind Dead? If not I wouldn't worry too much.
The sleeeve lenght is decent. Have in mind not a single jacket will fit the same way on different people, when you see pilot pictures you'll notice that everyone is wearing different sizes, contracts, etc. plus every single one of them has a different height and arms lenght. It's impossible that a RTW is going to fit perfect in every aspect of it. Chances are that if it was long in the arms you would find something else to nitpick about.
Personally, too long sleeves are kind of annoying for me to wear
