I wasn't going to post anything about the last set of pictures until I saw some of the comments about the way she is holding her cig (and the way she looks in gen.).
JEEZ, this is so ridiculous. I have about a thousand pictures of my friends (who smoke) in this same exact pose! I can guarantee you, they weren't thinking "I should hold my cigarette like Edie Sedgwick!" I tell ya, it just the way some women hold the darn cancer sticks!
And also...Edie's eyebrows were ALOT darker than Sienna's.
Anyway, what's so bad about filling your brows in? Last time I checked it wasn't a crime. I do it everyday and that doesn't mean I'm living in 1966.
