Opposition Leader Tony Abbott has endorsed Germaine Greer's criticism of how Julia Gillard dresses.

A fortnight ago, while she was a guest on the ABC's Q&A program, Ms Greer said the Prime Minister's jackets did not fit and were not flattering.

"Every time she turns round, you've got that strange horizontal crease, which means they're cut too narrow in the hips," Ms Greer said.

"You've got a big arse, Julia. Just get on with it."

Now, vision has emerged of a woman asking Mr Abbott about Ms Gillard's jackets at a community forum in Sale on Tuesday night.

Mr Abbott responded: "Germaine Greer was right on that subject."

The Opposition Leader's office has not responded to inquiries about the comments.
