Sigourney Weaver is an actress who needs no introduction. She's tall and smart and often kicks some serious ass in her films. She's nearly 6' tall (1.82 m) and holds a Masters of Fine Arts degree from the Yale University School of Drama. She's also completely believable as the cautious but steely Warrant Officer/Lieutenant Ripley of the "Alien" film franchise. She's proven herself to be brainy, beautiful and baddass.
Also, she wore a very thin, clingy white top and a pair of ill-fitting cotton panties toward the end of the original Alien movie. Of course, it was still the '70s so maybe undies were designed for maximum butt-crack exposure back then. Or maybe that's what they'll be like in the future. Or both. I'm not complaining.
These pictures are kind of a hodgepodge of movie stills, publicity photos and pictures of her hanging out on the set, but all of them show Sigourney Weaver wearing very little. Obviously, some of the pics aren't taken directly from the film because I don't remember Ripley putting on her helmet and then standing there all sexy-like before deciding to battle the Xenomorph which was hiding about ten feet in front of her.
It's possible the scene is in a version of the film that I haven't watched, but I don't remember a thin strip of cloth barely covering her nipples while she was in hypersleep either. Is it so cold in space that restraints are needed to hold Ripley's nipples down? Again, I'm not complaining. Wait, yes I am.
