From the North American Schachenmayr website:
If you love unusual clothes, then this mini-dress in Schachenmayr select Extra Soft Merino Color is a real find. Not knitted from the bottom to the top, but from left to right, giving it horizontal stripes that are very flattering to the figure. This optical impression is reinforced by individual rows of garter stitch which stand out like ribbed rows from the smooth stocking stitch of the dress. The result is eye-catching!
