OPI's A Great Opera-tunity (great name!), is a beautiful dusty peach polish with a crème formula. This polish was fully opaque in just 2 coats, with no issues of streakiness, bald spots, etc. I think that A Great Opera-tunity is an excellent office-appropriate polish, but I don't think that it's boring at all. Although you could easily jazz up this mani with a glittery accent nail if you wanted it to be a bit more exciting.
We have another great neutral polish! I've been really impressed with OPI's Venice Collection so far, and A Great Opera-tunity is one of my favourites.
Are you a fan of neutral polishes or do prefer something a bit more exciting?
