'Matte About You' is a topcoat by nail polish brand Essie. The best thing about it is not that it makes your manicure last longer but that it makes your shiny nailpolishes matte! I used it on a very pale light grey color, with the mattifying topcoat they look like they are made out of cement and feel like a chalkboard. Many brands carry a topcoat with a matte finish. Also, check the men's beauty department for transparent matte nailpolishes.
