This is probably the prettiest nail varnish i own, and the only O.P.I one too. It's part of the Alice in Wonderland range that came out a year ago?
Called 'Thanks So Muchness'
The picture really doesn't do it justice, but it has a lovely shimmer to it
I actually purchased this in Disney World last year for $10 compared to £10 :)
I'm loving the new Pirates of the Caribbean range, may have to invest at some point, they look so pretty
