Silly question, but ...

Does anyone when wearing a T-Shirt or any shortsleeve shirt for that matter have one sleeve that appears higher up then on your other arm, both my arms are the same size, but it seems my right sleeve is always higher up, why is that???

Either the shirt wasn't made symmetrically...

Or you're shoulders or traps are different in size.
