I really like the retro-look of this shoe.  I ordered a 7.5M but the heel slips a little.  If it weren't for the crossband, it would probably fall off completely.  I would have ordered a size 7, but they did not have it in Burgundy and I worried if the toe area would be too cramped in a smaller size.  I will buy some heel pads for this shoe to stop the slipping.  The shoe is light-weight, elegant and and I love the color.
