Available in white or black, this haute couture frock responds to the wearer's heart rate by clearing things up a bit. Yep, the Intimacy 2.0 turns transparent according to how you're feeling about the people around you.
The dress is made of leather and opaque smart e-foils that can become see-through. The foils react to variations in electric current.
The dress creator says, "Social interactions determine the garment's level of transparency, creating a sensual play of disclosure." You would have to be pretty comfortable with your own nekkidness to wear this garment out in public, but that's probably why it's not available at Macy's.
Studio Roosegarde suggests donning the Intimacy 2.0 for a stroll down the red carpet at your next film premiere. You can check out the vaguely-NSFW-depending-on-who-your-boss-is YouTube video of the dress in action.
Now, I'm just waiting for them to come out with Intimacy 2.0 pants for dudes that will answer the boxers or briefs question.
