Loving the purple/gold holo glitter polish from Color Combos! Problems with such polishes (faceshop, other korean brands etc) is that they don't have a name like OPI, China Glaze, Essie etc did. Names are easier to remember and more funky!
Anyways, I used Essence Ballerina's Charm as base colour and the holo gliiter is Color Combos CMT301. I added silver hex glitter to better define the "waves", if you can tell. LOL.
