Don’t donate those Jerry Seinfeld jeans to the Salvation Army just yet.

Lighter-blue “washed” denims, often with a looser fit and a higher waist — call them “dad jeans” — may be in fashion again. They have been popping up in street-style blogs like Tommy Ton and the Sartorialist, as well as at fashion-forward retailers like Acne, Supreme, J. Press York Street, Baldwin, Billy Reid and A.P.C.

Some of those high-fade models would not look out of place on President Obama out biking.

It may be premature to declare an end to the era of skinny jeans, the low-slung, raw-denim crotch tourniquets that have ruled the streets of Brooklyn lately. But designers who cater to selvage-denim snobs are detecting a shift in tastes and a step toward lighter washes and fuller pant legs.

“We’re definitely seeing more of a washed look, a longer rise, a little fuller thigh,” said Tyler Thoreson, the vice president for men’s editorial and creative at Gilt, the flash-sale site. “The edgier guys are going with a drop-crotch taper look.”

Part of the shift might be attributed to the cyclical nature of fashion.

“It’s a backlash against the now-ailing Americana-urban woodsman trend,” said Brad Bennett, who runs Well Spent, an influential men’s style blog. “Dad jeans are pretty much the total opposite, and thus, a quick and easy way for people who don’t want to be associated with the lumberjack look to distance themselves.”
