I am going to say it: Color Club makes the best mainstream holo polishes. Seriously. Look:
This is a Second Look Post, which means I have featured this polish on the blog before, but because it is SO beautiful, it deserves a second look.
This is Over The Moon, from the original Color Club Halo Hues collection. This is TWO - yes, two - coats of polish and topcoat.
The formula is PERFECT. Sorry for so many caps in this post, but I think they are well deserved!! I don't reach for this polish nearly enough, but I really should. These photos were all taken outside, in full sun, with (obviously) no need for flash from the camera. SO pretty!
You can find Color Club polishes online, so get to hunting!
