Cut-out detachable jeans are as awful as they sound

It’s official: 2017 is the fashion apocalypse. Cut-out detachable jeans that are basically a denim diaper with zip-on, zip-off legs have joined the parade of terrible that includes clear plastic trousers, faux mud jeans and rompers, aka romphims, for guys.

The latest double-duty demin doozies come in bleached blue or black, and are equally absurd from the front and the back — which is all about celebrating underbutt. Thank (or not) the design folks at Y/Project and Opening Ceremony, where the two-in-one trousers are on sale for $425.

“High-waisted saddle-shaped shorts? You could have the hottest body in the world and still not look good in these,” said New York style expert George Brescia, author of “Change Your Clothes, Change Your Life: Because You Can’t Go Naked.” Unless “you want to make an aggressive choice to look horrible,” he told the Daily News, “detach yourself from the idea of wearing them.”
