Agreed that the posing isn't that flattering. But it's very "avant-garde," and I feel like that's been very prevalent again in fashion photography, i.e., awkward, funny, discordant, poses. I've been seeing this "posing style" a lot around Dazed, Purple, Cake etc.
I could just be really wrong and out of the loop though, I don't know
Also, some of the other photos from that series are beautiful.... well, maybe only the second to last one.
Wow, it definitely looks like she has gained. I remember seeing her in real life a couple of years ago. Her body was phenomenal. I tried to sneakily keep an eye on her to see if she would eat the free food we were given. IIRC she did. I guess it was mostly her teenage metabolism keeping her skinny.
