Alicia Loren is another. If you can find her obscure/rare early appearances she is quite thin and much smaller breasted.
Will have to look out for that. I mainly know her in her "large and in charge" mode.
Susie Wilden lost a lot of weight but her breasts stayed the same as they were when she was bigger (I remember her celebrating this in an interview).
I think the Boobpedia account is most titillating:
"She is an all-natural voluptuous beauty who steadily gained weight from her debut in 2001, when she wore an
34E cup brassiere. By 2003, she had gained between 30 to 40 pounds, most of which was in her tits which ballooned up to a
G cup.
Susie's boobs had gotten so big at one point that she was buying
36JJ cup bras in the U.K. In 2006, she began losing weight and has since slimmed back down. Despite the weight loss, she is still considered by some to be the very definition of voluptuousness."
Sarah Rae lost a bit of weight recently but the change is relatively subtle. Devin Taylor was always a bbw but she slimmed a bit just to accentuate the hourglass aspect.
Another model whose weight loss was mainly for health reasons: the inimitable
Taylor Stevens.
