Different Nail Polish Finishes

Creme - a colour that has no shimmer/glitter/holo. Often mistaken as Matte. Take a look at OPI Gotta Get Pink!

Matte - A polish that dries matte, no shiny. Please do not get Creme and Matte mixed up :D
Neons often dry matte. Take a look at Matte Grape

Holographic - A polish that has rainbow coloured glitter and they look amazing in the sun! Take a look at Worth The Risque or under the 'Holographic' label :)

Holographic Glitter - A polish that has scattered pieces of glitter than shine different colors of the rainbow. Take a look at OPI Text Me Text You

Shimmer - A polish that has little bits of different coloured shimmer to the base or very similar to the base colour. These can vary quite a lot. Take a look at Misa No Shrinking Violetta and Superstitious or Pretty and Privileged

Frosted - A very smooth and fine shimmer. Take a look at OPI Suzi & The Lifeguard and Tangerine Scene for an example

Pearl - Similar to Frosted but has a somewhat pearl quality to it. Take a look at Misa Little Tease

Glitter - A polish that has chunks of glitter, often bigger and grittier than shimmer. Take a look at Cherry Much In Love, Emerald Sparkle or Midnight Blue Glitter

Neon - a super bright polish that usually dries matte. If they are sheer, you can layer them over a white. Take a look at Pure Energy, The Grass Is Greener On My Side or Pink Flame

Sheer - a polish that is usually used for French Manicures, designed to show the white tip. Take a look at Ready To Wear, Bailey and I'm Yours.
