Jeri Ryan's Seven of Nine costume is surprisingly made out of a thin, silky material. We were expecting a more plasticky material.
MIT researchers are currently working on a spacesuit with a similar design to the Seven of Nine suit. The idea is that skin-tight spacesuits provide the needed counter-pressure without the bulk of traditional, air-filled suits. The Gravity Loading Countermeasure Skinsuit (GLCS) is made of an elastic mesh.
