In an apparent effort to ensure that even plus-size douchebags can dress the part, two companies considered unlikely bedfellows — Ed Hardy and Hardee’s — have announced the launch of a joint venture, Ed Hardee’s.

Clothing designer Ed Hardy and fast food chain Hardee’s will open 10-15 stores nationwide in the next 18 months, offering what they say are one-stop shops for the “thickest burgers and sickest plus-size couture.”

Ed Hardy has recently been looking to tap into the customer base of people who care enough about their appearance to spend $120 on a T-shirt … but not enough to spend a quarter of that on a monthly gym membership.

Hardee’s has recently gained notoriety — and been vilified by some as a face of the growing obesity epidemic in the United States — for menu items like its Monster Thickburger, which contains 1,410 calories and 965 grams of fat.

Given those trends, Hardee’s CEO Andrew Puzder said the collaboration makes good business sense.

“Think if, like, Lane Bryant or Casual Male XL had super trendy clothes with lots of skulls and stuff on them,” Puzder said, “and had all-Angus burgers.

“How baller would that be?”

Not that “baller,” according to most market analysts, who are bearish on the new venture. The marriage makes little sense, experts say.

Then again, neither company has a history of what most would consider good business decisions.

Ed Hardy charges $75 and up for T-shirts that, according to one industry expert, “Look like they could’ve been made by some dude at a carnival or on the Boardwalk with a paint gun and some stencils.”

Still, the company has achieved mainstream success.

Hardee’s, meanwhile, has made a name for itself recently with unconventional and often controversial decisions in marketing and advertising.

Several Hardee’s advertising campaigns in the last decade have been criticized by groups for their sexually suggestive nature. Recent campaigns include “More Than a Piece of Meat” featuring scantily clad women appearing to receive sexual gratification from consuming Hardee’s products, and “Name Our Holes” — an ad campaign and website promoting Hardee’s Biscuit Holes.

Just as many observers wondered how television spots featuring Paris Hilton holding a burger and writhing on the hood of a sports car were supposed to sell high-calorie hamburgers, plenty of people also are questioning the viability of Ed Hardee’s business model.

Puzder seems unconcerned.

“Hardee’s is bold; we sell Thickburgers,” Puzder said. “And Ed Hardy is bold, too. They sell shirts with skulls and fire and stuff.

“So if you want to tell everyone that you’re super bold and that you spent $139 on a burger, shake, curly fries and T-shirt with spider webs and an exploding dollar sign on it, then Ed Hardee’s is for you.”
