OPI Happy Anniversary is a gorgeous pearly, shimmery white. It is sheer so I layered it over OPI's Alpine Snow and I found that it creates a cool, kind of icy effect.
I can't decide if I prefer to wear this combination in the Winter or Summer. If you have a deep tan in the Summer I think it would look great against it. But the iciness reminds me of Winter. Mmm, I guess that makes it a year round colour!
