Hailey Bieber must've sensed that I have a nail appointment on the books and no idea which color to choose, because she just served up the perfect shade of dark, smoky, moody blue—exactly what I'm craving this month. Thanks, Hailey!

Bieber is pretty loyal to her signature subtle glazed nails and variations thereof, but she also loves a well-timed nail surprise. That's exactly what she delivered in an Instagram Story on January 15, which doubled as a shoutout to her pal Kylie Jenner's new Cosmic Intense perfume. In the snapshot, Bieber holds the (truly gorgeous) sculpted red bottle in her hands, and the contrast between her midnight blue nails and the orange-red perfume bottle is really striking, making her nails pop even more.

Just a few days after attending an awards ceremony in a silver couture gown with silver cat-eye nails to match, Bieber changed up her mani aesthetic and chose a creamy, satiny deep blue, somewhere between sapphire and navy with a slightly dusky tone like the night sky. Her nails were slightly shorter than usual, filed into her preferred soft almond shape, and the dark blue color just so happened to perfectly match her top, which you can see peeking out of the edge of the pic. (Was that intentional, just a coincidence, or maybe even the inspiration for the color itself?)

Bieber's midnight blue nails are, of course, right on trend. This winter, we've been feeling saturated nail polish shades like her chosen dusky blue hue, including emerald green, dark or shimmering violet, and decadent chocolate brown—colors that feel mesmerizing in their depth and intensity, with a richness that really sings in the winter months. And now, thanks to Mrs. Bieber, I know exactly which color I'm going to choose at my next nail appointment!
