Climate change is a big issue, but hipster clothing brand Opening Ceremony might have a way to battle it, at least on a personal basis. Hail the latest denim design offered on its site and designed by Parisian company Y/Project. Dubbed the “detachable cut-out front jean,” this two-in-one slim pant converts with the flick of a button to high-rise cutout shorts. The variation on the jean comes in bleached denim for $425. For those who prefer a darker wash, there’s a side cut-out version in black for $460.

So when to wear the basic twofers? Let’s set the scene. Say you’re moving and grooving on the dance floor one hot summer’s eve, and, to steal a phrase, it’s getting hot in (t)here. Just unbutton the detachable legs of your pants, and voilà: You’ve got short, short booty shorts.

To be honest, convertible clothing has been around for a long while, especially in the sporty/hiking arena where jackets change into vests, and long pants transform into shorts, but, ahem, not like these.

“The idea of not-your-average-jean is a thing this season,” says Avril Graham, Harper’s Bazaar executive fashion and beauty editor. “Whether it’s mud-spattered jeans, zippers running up the entire back leg, clear plastic knees or these convertibles, it’s a trend that is around. And we’re going to be seeing more of it.”

Like ’em or not, Graham sees a practical upside to the jeans’ dual nature: “The great thing is if you have cold air-conditioning on one side and not on the other, you can keep one leg on,” she says jokingly.

They’re available at openingceremony.com in the appropriately captioned “denim reworked” section. Get ’em while they’re hot . . . or cold, as the case may be.
