About her growth... Based on pictures of her through the years, her growth was gradual, but steady. You can see the change when you compare her earliest run of photos taken at age 18/19, to pictures of her in 1975 when she appeared in the movie Linda Lovelace For President (she answers a phone while in a tub), then at age 30 when she posed as Rinah for Oui in 1979/80. 1980 was also the year she posed for Playboy in the Dudley Moore layout where she's sitting next to him in a sauna. In that 12 year span her growth is gradual and evident. In the early 80's she appeared in a number of TV shows, and by 1986 (age 36) in the movie Hell Squad where she's wearing a white tank top. In that movie you can see considerable breast growth when compared with the early 80's. Then 6 years later in 1992 (age 42) she appeared on Up All Night with Rhonda Shear, where it's evident her seams are bursting. Beginning in 1993 she began modeling again as the mature marvel, Alexis Love. Her physique continued to grow even more over the following years, which she mentions in a mid 90's interview with Steve Sullivan, saying clothing she bought a year before no longer fits her. The images of her in the Ultra Vixens video at age 49/50 are the last public nude photos of her.
When I look at all those pictures, I see a gradual, steady breast growth along with overall body weight increase. As her title states, she is most certainly a natural marvel.
