OPI Katy Perry Collection
The best way I'd describe Last Friday Night is a translucent, pale cornflower blue jelly polish loaded with glitter reminiscent of China Glaze Snow Globe. There are similar polishes that replicate or come close to achieving the iridescence in Last Friday Night (not only Snow Globe, but Revlon Heavenly, Essie Shine of the Times), but none of them have the same ethereal, barely there blue base. It really adds something extra to the polish and makes it more unique.
I painted 4 coats which I feel is the minimum required to wear the polish on its own, rather than using it as a top coat. I did try it over a navy blue polish, and while the contrast made the glitter pop, I felt it lost the character of the polish. If I wanted a glitter top coat, I'd just use any of the other polishes I mentioned that have a clear base. I get that not everyone will have the desire, patience or time to paint 4 coats (not including base and top coat), but for Last Friday Night, the result is worth it. Surprisingly, my manicure has lasted a few days without any chipping or signs of wear. I'm not sure if this is because of the base and top coat combination I used (Revlon Colorstay Gel-Smooth Base Coat and of course, Sally Hansen Insta-Dri), or whether the polish itself has excellent longevity. Probably a bit of both.
