I've pretty much given up on ever trying to get Enchanted Polishes now, well unless another Beatles polish comes out, so I've ended up just going to my collection and putting holo top coat on colors similar to colors that have been released by Enchanted Polish.
I think back in August or September, they released a burgundy holo so I picked up OPI's Every Month Is Oktoberfest and layered some of Starlight Polish's holo top coat in Starlight on the top. The effect was beautiful! The shimmer came through the holo and it was awesome. It's not really a dupe at all of the Enchanted Polish but it was a fun alternative and a good reminder that I have SO many options within my own collection.
This manicure sort of speaks for itself in photos - Starlight is a very vibrant polish that has larger almost non-linear pieces of holo. It's still linear though, and looks amazing over almost every base and in the sunlight. Starlight Polish is available on her Etsy store.
I used OPI Nail Envy as a base coat and Seche Vite as a top coat. It lasted about 4 days before I removed it and did something else with my nails.
Do any of you have a favorite holo top coat? What's your favorite holo combination?
