It says that she has a 21 inch waist, but I don't think that's accurate. Her waist looks like it's around 22-23 inches, judging from the video in the link you posted. I think she's pretty though, she has a lovely face
Okay so I know there's a debate going on about her in the Before-afters thread (and not commenting on her personal issues or lack thereof since there is no proof either way) but aesthetically I think she is fucking gorgeous.
When she is skinny, she is GORGEOUS (I agree that a bit of gain really makes her a bit average for modeling standards). But those legs, God. And such a nice xylo + tiny waist. I love when a girl can still look cute when she's bony.
