Cpalmson,
It isn't a matter of subjective beauty. This girl got me all hot and bothered despite her dimensions. I could say she's 5'6" and 150 lbs but it could be 170 and I ain't gonna ask. It is more in the descriptive possibilities. With all deference to those who suggest MM or Cindy Crawford are BBW's, to compare my friend to those icons of beauty is both laughable and inaccurate. My friend may be a size 10 but she is multiples of my size 2 (or 0) ex.
What I'm searching for is a reasonable label or description so I can write a credible review that conveys both her "thickness" and her beauty. The cliches and norms of facial beauty are easy but not so for heft. I thought Rubenesque might work since P.P.'s works are accessible on the internet, but sadly the adjective might be missed by many.
There has to be a word or phrase that captures this girl's body type that is accurate but not perjorative.
