A while ago I bought Chanel's Paradoxal, from the moment I saw pictures, I just knew I had to have it. And I still don't regret splurging the $$$, because I have a thing for this purple taupe with its secret shimmer. The wear has been great on me and I actually wear this every now and then.
What exactly is considered a dupe anyway? According to the dictionary a dupe is a version identically copied from an original. So when you compare these colors, they have to be fairly identical before you can label them as dupes. This is why I don't consider Models Own's Purple Grey and MNY's #549 exact dupes of Paradoxal. Their base colors are definitely similar, but they're lacking any type of shimmer. MNY tests on animals anyway, therefore it's not even an option for me.
the fun without the $$$
While I love Chanel, I have to admit: it is kinda pricey. Thankfully I've come across some cheaper alternatives: Barry M's Dusky Mauve and number 509 by Hollywood Nails (they even share the same number!). If you look at this comparison you'll notice how close Barry M and Chanel are! They have the same base color and pretty much the same amount of shimmer. The camera shows more blue in Barry M's shimmer, but I looked very hard and didn't notice this myself. #509 by Hollywood Nails is pretty close too, but the shimmer is different: the particles are smaller and more evenly distributed throughout the polish.
The application of Dusky Mauve and Paradoxal is also quite similar, they both need 2 layers and they go on very nicely. #509 by Hollywood Nails is almost a once coater, win!
Chanel Paradoxal costs $23.00 for 13ml, Hollywood Nails #509 costs $4,25 for 15ml and Barry M's Dusky Mauve costs $4,75 for 10ml.
So, if you fell in love with this color too, but you don't want to hurt your wallet, I'd definitely recommend Dusky Mauve by Barry M, I actually consider this a dupe and it's not expensive at all! Yes, the one by Hollywood Nails is relatively cheaper and has better coverage, but I still don't know where you can buy it as it's mostly a salon brand.
