A little while ago, I stumbled upon a bottle of Chanel Paradoxal. Never one to pass up the opportunity to do a comparison post, I went out the next day and found Revlon's dupe, Naughty. In viewing other comparisons online, it seemed to be that Naughty didn't have quite the same shimmery depth as Paradoxal, so I had to see for myself!
Pretty similar here. The Chanel looks a little more sparkly, but that could just be the bottle shape.
Surprisingly similar. The Chanel version has a slightly longer handle and the bristles are a little shorter, but that's about it.
And finally, the swatches:
I have Chanel Paradoxal on my pinky and middle fingers, with Revlon Naughty on my ring and index fingers. Quite honestly, I can't tell which is which! They are practically identical, from the subtle pink shimmer to the gorgeous greyish purple. The Revlon version might be a touch darker in this close up shot, but I could not see a difference in person.
Application for both was very similar - no real issues at all with either formula.
In this case, we definitely have a true dupe. Unless you're really concerned with the label on your polish bottle, you can safely skip the $25+ on the Chanel, and pick up the Revlon. I've seen it on sale for as little as $3 a bottle.
