i posted earlier about my comparison between these two polishes. i ultimately decided to purchase both polishes to layer. both polishes are navy blue jelly bases with pink-purple shimmer, but the Milani polish has larger shimmering particles. i did two coats of Rimmel "Night Before" and one coat of Milani "Totally Cool" on top for extra pink shimmer. i have to say, i really like the brush on Rimmel 60 Seconds polishes. it can be kind of nerve-wracking applying a dark jelly, but the Rimmel brush is very easy to use. i had no problems with layering these; they dried quickly and nicely with a coat of Seche Vite on top. i'm very pleased with the outcome...so much so that i didn't want to watermark the photos i took.
i love the bottles too!
