This link includes the pictures that Berkley posed for in 1995 concurrent with the film’s release. It’s quite an extensive collection of film captures, behind-the-scenes material, promotional poses, etc.

* She spread her legs for photographer Bettina Rheims: “Elizabeth Berkley stuck in bamboo bushes, Los Angeles, 1995.” The top link includes a good version of that Bettina Rheims photo. According to ArtNet, the original exhibition version photo was 4×4 (feet)!
* And she posed for Esquire in body paint. The HQ version of the Esquire pic, minus the text, is in the first link, but the actual Esquire link is worth visiting, because the text is funny. (A suggestion for Showgirls tie-ins.)
As you might guess, Elizabeth Berkley has been mentioned here a few times before.

Esquire “Must sign in to continue”
You can read the text on the photo without logging in (Or at least I could, and I’m not a subscriber.).
She died her pubes for it?
