New York, Feb 8 : Hillary Clinton has not yet selected the outfit she will wear at daughter Chelsea's wedding.

"Well, if you don't tell anybody ... we're still looking," the New York Daily News quoted her as saying at CNN's "State of the Union" talk show.

The Secretary Of State added: "I don't have a dress yet, no, and Chelsea doesn't either. But we're working on it," Clinton added.

In November 2009, Chelsea Clinton, 29, had revealed she would tie the knot with investment banker Marc Mezvinsky.

She had sent an email to pals saying: "We wanted to wish everyone a belated Happy Thanksgiving! We also wanted to share that we are engaged!"

Chelsea and Mezvinsky, 31, have been seeing each other for four years.

They met when the former First Daughter was in the White House and both Mezvinsky's parents were in the Congress.
