Orly Sunglasses at Night is part of the Flash Glam FX collection. All of the polishes in this collection are really different, designed to be layered over the top of another polish. I think that they are quite similar to a lot of indie polishes which are out there.
Difficult to photograph, which is why I have a video further down. Over ELF Black.
Sunglasses at Night is basically a holographic strand polish in a sheer watery grey base, perfect for layering over black. Was a bit of a pain to work with as any flitter type polish is, that was because the bits of glitter were extending past the end of the nail. Really like Orly polishes as the bottle has a rubberised lid which makes it so easy to open, and to keep it in your hand for perfect application.
Out of focus to show of true holo strands
