I already posted a few comparisons of the new NARS Douceur Blush for fall, (see my comparisons here) but many of you are curious for even more comparisons to Zen and Madly. Here are pics of the blush comparisons you requested. They are all different in my opinion. Douceur is a dusty pink-brown. Madly is a beige with slight shimmer and pink tones (on my face at least). Zen is a straight nude-beige-brown. Ninotchka goes on me a brownish color.
Swatched heavily over Chanel Teint Innocence Liquid Formula in Shell 1.5 to pick up the color more: Douceur, Madly, Zen, Ninotchka.
