In a time when I thought I would literally never run out of nail polish -- that is, before I proudly decluttered to thirty bottles, go me -- I still managed to find a reason to repurchase a few.
Chanel Blue Satin / Vendetta - Blue Satin was my first dark nail polish, my first Chanel purchase, my first bottle I legitimately used up. I've lamented several times before that black nail polish never actually looks black on me -- I need the cool tone of a navy to give me that inkiness that just screams chic. And I never use that word. They released Vendetta, a purple version of Blue Satin, and honestly, you don't need both. I'll probably go back to Blue Satin after I finish this bottle of Vendetta.
OPI Quarter of a Cent-Cherry - This is my perfect red. It's perfectly midtoned with just enough blue to balance the skin tone in my hands, keeping them from looking too red, too ashy or too muddy. This was released in 2008 with the 25th Anniversary collection, but I think most displays still have a few kicking around. That said, I dropped my only bottle a few years back and have been hoarding it ever since. It looked like a scene from Alien -- or at least what I imagine the Alien trilogy to look like.
Nails Inc Baker Street - I have a weakness for blue/turquoise/green, but for some reason this particular blue -- a neon-level bright cobalt that leans slightly periwinkle -- this incredible colour is a game changer. In my entire nail polish career (can we call it that?), I've never felt so strongly about a blue, and that includes OPI Dating a Royal, which was the first blue I ever purchased. That one will always hold a special place in my heart, even though I don't feel the need to keep it in stock. That said, I just threw out a half-empty bottle of Dating a Royal, but I've run through half a bottle of Baker Street in less than six months.
