Just a few days ago, I was looking at someone's nail-art blog, and they had some polishes by Essie. And then... as if she had known I was wishing for a bottle... my sister sent one to me by mail from Canada!
"Lilacism" by Essie (shade 304)
Essie polish is definitely not a one-coat wonder, but the formula's not bad. I much prefer it with a topcoat, because the finish is very matte. I don't have many pastels in my collection at the moment, and Lilacism is a lovely shade, though with the blue undertones I wouldn't say it's a true lilac.
