Melanie Griffith in nude scene from Working Girl which was released in 1988. She shows us her tits in sex scene. There is not much other real nudity but Melanie Griffith looks quite sexy in that underwear.
Also Elizabeth Whitcraft naked in Working Girl. We can see sex scene with her. So Elizabeth Whitcraft is not shy and she demonstrating her boobs.
If she had on some knee high black leather boots in that closet scene she would've been even sexier.
