Hello! I got my Nubar Jeans in the mail yesterday and I couldn't wait to get a comparison shot for you all. I only purchased one of the Les Jeans De Chanel polishes. Here is Chanel Blue Rebel in comparison to Nubar Dark Wash Jeans. Blue Rebel is on the index and ring fingers, and Dark Wash is on the middle and pinky fingers.
As you can see, they are incredibly similar. You might not even be able to tell the difference from the picture. Chanel Blue Rebel is just a hair lighter, but that is the only discernible difference. The texture and application of the Nubar polish is almost identical to the Chanel. They both need two easy coats to be opaque, and have a hint of gooey viscosity to their texture that makes them easy to control and apply.
Here's Nubar Dark Wash Jeans on its own:
Please try to ignore my hot pink sweater being reflected in these pictures! I should have worn a more neutral piece of clothing while I was swatching. =p
