A few weeks ago the world (via the Internet) wished Gloria Steinem a happy 80th birthday. I wonder what Ms. Steinem, pioneer of women's lib, defender of women's rights, etc., etc., would make of the Intimacy 2.0 dress.

The brainchild of an "international design firm" called Studio Roosegaarde, the garment -- available in black or white -- becomes more transparent when it detects sexual arousal.

Talk about putting technology to good use.

Made from leather and "opaque smart e-foils that become increasingly transparent based on close and personal encounters with people," the dress (that Judy Jetson would surely swoon over) reacts to the wearer's increased heartbeat and accordingly "social interactions determine the level of transparency, creating a sensual play of disclosure."

Translation: your heartbeat increases, your dress gets see-through. (Oddly, the press release neglects to mention that your heart rate might quicken if you, say, get mugged, or run for the bus and not solely because George Clooney, Ryan Gosling or Scott Smith offer to buy you a drink.)

Cool. Or, not. Take your pick.

Although, maybe if you paired it with the bra that won't come undone unless you're into the guy?
