Why not wear pajamas all day?

Retailers are jumping on the pajamas-every-day trend, with stores like Abercrombie & Fitch, Aeropostale and Pink, a sub-brand of Victoria’s Secret, giving loungewear prominent display. American Eagle Outfitters’ Aerie brand merchandises sweatpants, leggings and other relaxed styles with a variety of shirts, including those with asymmetrical hems or dolman sleeves. A wide neck is key, says Jennifer Foyle, chief merchandising officer, because “girls are wanting to show their bra straps.”

As with a lot of teen behavior, some adults are annoyed. In Louisiana’s Caddo Parish, which encompasses Shreveport, Commissioner Michael Williams is getting national attention for taking a stand. He plans to propose an ordinance outlawing the wearing of pajamas in public.

“The moral fiber in America is dwindling away,” Mr. Williams says. “It’s pajamas today; what is it going to be tomorrow? Walking around in your underwear?”
