I love this kind of "mermaid" colour, shimmery blues with a hint of green. I wouldn't exactly call this colour turquoise, although the shimmer flecks are probably close.
I found this polish much too sheer for the type of finish that it has. I had to use four coats for an opaque cover, and I think two should definitely be enough. I have other similar polishes with this colour and finish, and they all cover in less.
I think Austin-tatious Turquoise is very pretty, but not very unique, and somehow slightly disappointing.
