I got my LA Girls glitters through Cherry Couture, but I've seen a recent display at Rite Aid. I used Maybelline Express Finish Purple Trend as the base.
Here's Purple Trend by itself. If I ever make a top 10 list, this sucker is going to be on it. I love the vampy purple, but the teal shimmer is what makes it so special. Make sure to click to enlarge the pick.

and this is in order: Flamboyant (copper), Eutopia (purple), Nostalgic (aqua), and Jostle (blue). Each color has small micro glitter and larger hex glitter of the same color in a clear base.

Thanks for looking!
