Tim Gunn doesn't think Hillary Clinton is making it work! 

In an appearance of Lopez Tonight that aired Tuesday, the fashion expert mocked the Secretary of State's "Jersey Shore style."

"Why must she dress that way?" the 57-year-old quipped. "I think she's confused about her gender [with] all these big, baggy menswear tailored pantsuits."

"No, I'm really serious," he added. "[They're] unflattering."

When Lopez, 50, asked how the former New York senator could "hide her cankles," Gunn said it was just a matter of adjusting her hemline. "Well, if her pants didn't stop an inch above her ankle, she could hide the cankle!"

Gunn might not be a fan of the former First Lady's choices in clothing, but he is impressed by her work in politics. "I have great respect for her intellect and her tenacity and for what she does four our country in her governmental role," he said. "I just wish she could send a stronger message about American fashion."
