This is a styling method that decides, based on your skin tones, what colours look best on you. You can take it one step further and find out your style too which is based on body shape and personality preferences. I had mine a while ago so I knew I was a winter, because my skin has a green undertone to it (olive maybe a better nonmartian way of saying that!) . It means I can wear black, white, reds with blue undertones, but not oranges or most yellows. I'm actually a jewel tone winter, so the colours have to be bright, icey and sparkley. My "style" was Romantic Classic, so I can wear boho well (thank goodness), and tailored, but no sharp lines, more ruffley, think Carmen! I really like what I ended up with, although at my age, it wasn't a great surprise. Anybody else?
