Some of the sexiest moments on screen actually involve people keeping their clothes on (mostly) and a good thing that is too when you consider the seriously great style to come out of films such as Boogie Nights, Belle du Jour and The Night Porter. 

Plus, would scenes on The Secretary or Body of Evidence have seemed quite so steamy if the on-screen action wasn't contrasted with buttoned-up office wear, and you can't deny Sharon Stone's boy-hugging white dress in Basic Instinct is as memorable as what she flashes from beneath it.

BTW, NSFW - blame Madonna.
