After wearing a pastel lilac on my toes for a month I felt like getting some color down there:
That is two layers of Chanel Bel-Argus 667, no top. The first layer looked terrible, but the second evened it out. Bel-Argus is a shimmery dark blue, with a very subtle duo-chrome towards violet, although you barely get to see that. Bel-Argus was part of the 2013 summer collection.
