The Art of Dying (1991)
She appeared topless in close to a dozen films, but her appearances were T&A only, as far as I can recall without researching it. She did no full frontals, but possessed a chest we wanted to see again and again. (There was a brief glimpse of the top of her pubic hair in the open-matte version of Fraternity Vacation.)
Kathleen is 60 now. That might make you feel old, but probably not as old as it makes me feel, given that I used to have a teenage crush on her mother (Abby Dalton)!
She’s still working. Per IMDb, she recently co-starred in a web series called Phoenix, where she looks like this.

Didn’t she show her bush in the fullscreen version of Fraternity Vacation or was that just Barbara Crampton?
Glad you mentioned it because I was thinking the same thing. I remember seeing that scene on cable in high school and I always swore you could see bush. Whenever I’ve seen that scene recently it is cropped out. Only thing is I don’t remember if it was Crampton only or both of them.
Must have rewound her & Crampton mooning in FV about 200 times back in the day – I miss mooning scenes in movies
I definitely remember the hint of Kinmont bush and think there was Crampton’s too.
Also, how many of you remeber the scene was with young Nuke LaLoosh?
Crampton’s pubes were only seen in the open matte, full-screen version which was broadcast on early cable and appeared on the VHS. Every version since has cropped out that brief peek of Crampton’s crotch. Kinmont is only seen from the side in that version, but you can make out her pubic hair in yet another full screen version, which is even in HD!

I would still choose her over Shauna Sand. Lorenzo Lamas, what a moron.
