There are soo many polish finishes (finish not polish) I thought it would be handy to have a list of some of the more common ones. Feel free to add any I may have missed!
Creme Most popular polish finish (unless your a glitter lover like myself). Plain (boring) colour without any glitz, or sparkle added. Dries glossy and smooth. Think grown up job appropriate.
Metallic dries to a finish that's look like metal (think coloured stainless steel). Very shiny.
Matte dries, with no shine or sparkle at all. (strangely, I love it)
Suede dries matte, but(!) has a slight shimmer (best of both worlds).
Shimmer metallic meets creme and dries shiny.
