You’re more right than you know.

The 1975 third-draft script has Leia interrogated by Vader and two other Imperial officers: a scene modeled on a deleted scene in THX 1138 which survived in the novelization, where LUH is raped by three prison guards.

Not to mention several of Ralph McQuarrie’s thumbnail sketches for the chasm-swing scene show Leia bare-breasted and wearing only a tattered skirt. (And another 1975 McQuarrie “wardrobe malfunction” sketch of Leia in prison is the frontispiece to The Making of ESB.)
