No, the nail varnish usually doesn't last a whole week. Usually on a Wednesday or Thursday I have to replace it with a quick fix, which is a something like a light pink or nude nail varnish.
No, I never leave the house without nail varnish. Addicted? Yeah, maybe ;-)
Base coat: essie 'rock solid'
Base colour: L'Oreal 211 'Opulent Pink'
Polka dots: Evie Mai base coat
Top coat: Maybelline Express Manicure
After the pink dried I took my dotting tool and got dotted away ;-)
