Rikugien is a muted rose shade which looks almost neutral on my dark toned lips. I love how it makes my lips look natural but better when I want something that doesn't scream attention.
Upon close examination, I thought it look pretty close to another favourite shade of mine from NARS, Dolce Vita. So here I am comparing the swatch of Satin Lip Pencil in Rikugien and Sheer Lipstick in Dolce Vita.
Top: Dolce Vita, Bottom: Rikugien
I find both shades close but not exactly the same as Rikugien has a more pinkish tone.
I'm not sure about you but here I am thinking what to get for my third Satin Lip Pencil! (opppsss...... drawer full of lip products staring right back at me -_-)
