Orly "Oui" is a lovely purple/gold foil polish. It's similar to OPI "It's My Year" but with a bluer base. It's pretty awesome if you love purple polishes with a twist, depending on the lighting it can look more purple-y blue or more plum:
You'll need two-three coats (I think I did three in these pics) to get the color completely opaque, but it's absolutely worth it. I think the color looks very festive & oh so sparkly.
Thanks for looking :-)
