Naked & Famous thermochromic jeans
This brings a new meaning to the term "hot pants." Naked & Famous

New for spring, jeans maker Naked & Famous is rolling out color-changing pants made with thermochromic dyes. A molecule inside the dyestuff reacts to heat, changing colors depending on how steamy hot or frigid cold you are. The colors fade between blue and white.

The biggest concern with color-change jeans is how the color-changing properties might highlight certain assets you might not necessarily want to bring attention to. You might remember Hypercolor shirts, a fashion fright that boomed in the early 1990s. They had a special way of showing off just how steamy your armpits were. However, Naked & Famous is trying to reassure us by saying, "Don't worry, the jeans change colors all over and not just in your 'happy areas.'"

These aren't just regular old jeans with thermochromic properties, they're selvedge, a heavier type of denim much sought after by aficionados of jeans. Between the selvedge and the special dye, you'll pay a premium price of around $240 to squeeze your butt into this color-changing fashion statement.

Let's think about who would want these pants. Anybody feeling nostalgic for the fashion of the '90s is a good bet. And I could see chemists having a blast with these. They would enjoy discussing the molecular properties that make the colors change.

Beyond that, we'll just have to see. I'm not expecting to spot these jeans on the hoof in the warm climate of New Mexico. That would really test the company's claims that they don't highlight your private hot spots.
