My recent obsession with nail polish is fairly recent, and my willingness to pay for high-end polishes is an even more recent development. So, of course, I missed out on last year's Chanel Jade. I honestly don't have a strong preference for Chanel polishes, but I do love mint greens, so I was pretty disappointed to see that it sold in the hundreds on ebay. I was pleased, however, to find out that there were some great dupes out there! I first found out about Catrice Sold Out Forever here: http://www.lushiousbeauty.nl/2010/04/catrice-nieuwe-nagellakjes-chanel-jade-dupe/
SOFE is the closest dupe in the comparison picture. It is not readily available in the US, but a friend of mine from Belgium was kind enough to send me a bottle.
Recently, though, Milani came out with a color called Dress Maker, and after seeing the comparison pics on Steph's Closet, I had to have it. It's available at CVS in a special display (or wherever Milani is sold), and also on their website. If you can't find it in a brick-and-mortar store, I highly recommend ordering it from the website as it is selling for quite a bit on ebay.
So, after buying both, I had to do my own comparison of course. Here they are, side by side (please ignore the lumpiness on my pinky, I broke it and had to use the tea bag method):
Yikes, my hands look so red in the bright sun! I have an olive skin tone so "lobster hands" usually isn't a problem for me, but these pictures would have you believe otherwise!
In the bottle, SOFE is slightly more on the sage side while DM is more minty. DM has more shimmer, SOFE's shimmer is more subtle. DM is slightly more sheer; in the pictures I am wearing three coats of DM and two coats of SOFE. Both formulas were easy to work with, but SOFE comes with a wide brush while DM has a thinner, standard brush and took a bit longer to dry (probably because it required more coats). On the nail, it's really hard to tell the difference between them except for the shimmer.
Overall, I love both colors and formulas. Of course, most people will not have to worry about which to choose since it's hard to find a place where both Milani and Catrice polishes are easy obtainable.
Hope this helps!
