It has armholes and a seam up the back (icky) and even a little body. In fact, i'm afraid it might be too little, but will knit a bit more before deciding to rip-it.
I'm wondering if the center line through the garter couldn't be eliminated by alternately where the transitions between knitting and purling fall--one row after the marker and the other row before the marker. Any thoughts? Maybe I'll try it on the sleeves.
