Definitely not Invasion of the Bee Girls - one of my all time favourite B(ee) movies - but you may be thinking of Lifeforce (1985), the very loose adaptation of the Colin Wilson novel, The Space Vampires. And it just happens to be another of my favourite B-movies.
In Lifeforce, a vast alien spacecraft is discovered hidden inside the tail of Halley's Comet. Inside are transparent crystal sarcophagi containing naked people, including the wonderful Mathilda May, who spends the entire movie naked and sucking the lifeforce out of people.
Warning: NSWF, significant French boobage involved.
