Yoko Ono can now add fashion designer to her list of accomplishments.

The 79-year-old author, artist, musician and innovator unveiled her latest fashion campaign with Opening Ceremony, a global clothing brand with collections for women, men and children.

The concept behind Ono's collection, titled "Fashions for Men: 1969-2012," began when she met designer and Opening Ceremony co-founder Umberto Leon three years ago in Tokyo. When Ono presented her idea to Leon, he decided to join her.

This week, Ono launches her limited-edition fashion line, which includes 18 styles with 52 separate pieces. The pieces were inspired by a gift, including a series of drawings and sketches that Ono presented to her late husband, John Lennon, on their wedding anniversary in 1969.

"I was inspired to create 'Fashions for Men,' amazed at how my man was looking so great," Ono said of her 1969 sketches. "I felt it was a pity if we could not make clothes emphasizing his very sexy bod. So, I made this whole series with love for his hot bod, and gave it to him as a wedding present."

"You can IMAGINE how he went wild and fell in love with me even more!" she added. "My sophisticated, tasteful, and sensible friends across the world all scream - 'We love it!'"

The collection includes jersey blazers, suit pants and hoodies, starting at $75. New York City stores have already stocked their shelves with the latest items. Opening Ceremony will carry Ono's collections in its Los Angeles, London and Tokyo stores.

"I think she just fell in love with John's body and wanted to show off all of the parts of his body that she loved," Leon told WWD. "There's something so beautiful about that sentiment."
