Polish swatches as promised! This post is specially for OPI Parlez-Vous OPI? It's a discontinued colour from the France collection but I got it from eBay! I'll be showing you comparison shots of it so you can get a rough idea of it's colour as compared to other colours! No dupes though!

Application-wise, it was pretty good, if I remember correctly it took 2 coats to get it opaque! I'm not really digging the colour just yet because it looks so much different in real life than the swatches online so I was a bit disappointed with the colour when I first got it in the mail! Colour-wise, the best description I can give of it is that it's a smoked out lavender. Hope you like the colour!
