BC: Revlon - ColorStay Base Coat
Color: Literary Lacquers - Sidewalk's End, three coats
TC: Seche Vite
When I think of sidewalks, I imagine a color a few shades lighter than this, but that's fine. Maybe it's a rained-on sidewalk? Regardless, Sidewalk's End is a lovely medium grey linear holo. It was a little on the thin side, but it's perfect in three coats.
Wear: Five days until noticeable chipping. (Though I was on vacation and wore it way past that point. Shhhh... >_>)
