There are two shades I am debating over. They are both from YSL and really similar but one is darker.
|YSL rouge pur couture noir laque|
|YSL rouge pur couture belle de rose|
She is wearing the darker shade but with a fun technique to lighten the look and make it look worn-in. Check out the Nasty Gal blog for the tutorial. I can't wait to try it myself!
