Definitely not Luftwaffe, for sure. As the other Steve said... there's a bunch of possibilities who wore this, but without more information it's not possible to say exactly without more information.
The loops on the left breast pocket are for the sports badge. This indicates it is probably, not not definitely, some type of German service jacket (civilian is not as likely). If you can find signs of anything being stitched on the arms or the collar that could help.
