Many of my favorite polishes are “almost black”; I especially love the red ones. Nailpolish that looks almost black but has a slight tint of another color is just sooo interesting.
OPI’s Midnight in Moscow was my first almost black and first self bought OPI. I’ve loved it for a long time but actually found two replacements that are better according to me, mostly because the red in them is more prominent. I guess that depends on how black you want your almost black to be 😉
