Hello ladies, I really need your opinions regarding the YSL preppy oxford pumps. 1. Is this style old-fashioned? 2. How can you dress them up or down? Or they're casual? 3. Are the red stitches tricky in the sense that you cannot wear any color with these pumps? Your outfit has to be either in black or black and red (e.g. red belt)? 4. Have these pumps been faked? 5. I bought a large Belle de Jour Clutch in black patent so would it match with these pumps? Or should I buy simple black pumps? 6. Is this style just for Fall? Thank youuuuuuuuuuuuuuuu ladies!
