Today I'm comparing two more colors that I have come across as possible dupes. They are OPI's Yoga-ta Get This Blue and Wet 'N Wild's Blue Moon from their Wild Shine line. In the bottle, you almost can't tell them apart. Take a look!
They are both dark teal blues with either a blue or green shimmer to them, depending on the light. On the nail, you really can't tell the difference. For my swatch, the OPI needed 2 coats, on my index and ring fingers, and the WNW needed three, on the other fingers.
See what I mean?! If you love the color, but don't want to pay full price for the OPI, get the WNW. It's available everywhere and is only about $2 US.
