I was trying to call my bank last night and was on hold for 20 mins. Plenty of time to do this little experiment and compare Chanel's Particuliere to Essie Mink Muffs :-) I don't think it's a dupe of Chanel but it's very similar. At least from a distance :-P And in the bottle! Here we have flash and daylight:
Flash you can see an obvious difference. Essie is darker but in daylight they look very similar:
Comparing the swatches side by side, it's hard to tell a clear difference and quite honestly if I were to go to work with one hand Chanel, one hand Essie, no one is going to say anything:
To me Essie looks more like a chocolate brown while Chanel is a more taupe brown.
I asked the boyfriend which one he liked better (without knowing which was which) and he picked the Chanel. Nice choice :-)
