OPI makes a great navy blue (Russian Navy) along with the rest of the brilliant colors in the russian collection...i couldn't find it at my local drugstore(s). i did, however, find Sally Hansen's Runway Collection which was inspired by fashion week in my fabulous hometown of NYC. the color i chose was Navy Venom and its actually been lasting wonderfully without chipping or fading. i've gotten several compliments on the color - as it is not black yet it is reminiscent a 1940's style.
i adore it and i think you would too.
yours,
