Besides the various shades of blue I wear during the spring/summer, dark nail polishes are my absolute favorite. Lincoln Park After Dark is my go-to nail color once the temperature drops below 70. It’s the darkest shade of purple that it’s almost black and completely perfect. It was discontinued a little over a year ago and I bought a few bottles to stock up for awhile.. and then my roommate also bought me a bottle for my birthday! You can still find it online on various sites including amazon. My other fall favorites are Black Onyx and Here Today Aragon Tomorrow.
