Frenzy is described as a lilac grey, and that's what I expected when I purchased it. While I can definitely see the lilac and grey undertones, I'd say it looks more mushroom-y in real life, like the perfect balance of taupe, mauve and dove grey.
I really enjoy the Chanel formula: it's light weight, self smoothing and, in this case, quite chip resistant - still perfect after 5 days of wear -. And doesn't apply streaky like other similar pale shades.
Overall is a very sophisticated nude nail polish, a new way to the mannequin style. I think it's best suited for lighter skin tones and considering the price tag and the particular shade, you may want to see it in person before buying.
I really hope Frenzy will make it to the permanent line because I love greys and nudes and this little hybrid here is a dream come true.
How do you like Chanel polishes? Did one of the fall shades catch your eye already?
