Hoppin Rib Quarter Zip

I enjoy the way the Johnny-O 1/4 zips look from the front but on the back of this one is a horizontal seam that I assume is necessary to turn the pattern on it's side and come up to meet the neck line. It's not shown in the photos but it does make the otherwise dressy 1/2 zip look more like a rain coat. The fabric also has a more spandex feel than I was expecting and although it's great for casual outings it's not something I would wear with a Johnny-O button up underneath to a business meeting
