Rosangela “Janja” da Silva, a 56-year-old sociologist, has noticeably changed her style since being thrust into the spotlight when her husband, veteran leftist Luiz Inacio Lula da Silva, took office on January 1.

The long-time Workers’ Party activist, who married the twice-widowed Lula, 77, last year, has glammed up her previously low-key look.

She has replaced her go-to jeans and sneakers with a wardrobe carefully chosen to champion her favorite causes, including women’s rights, Indigenous peoples and the environment — not to mention Brazilian designers.

“She’s made Brazilian fashion one of the elements she uses to construct her public persona as a feminist and progressive who cares about social issues,” says Benjamin Rosenthal, a personal marketing specialist at Brazil’s Getulio Vargas Foundation.

Da Silva has had the nation hanging on her fashion choices since at least her wedding day last May, when she and Lula paused a grueling presidential campaign to make their five-year relationship official in a glamorous private ceremony in Sao Paulo.

She walked down the aisle in a flowing white dress featuring a tiny red jewel in a star embroidered on the low-cut shoulder — a wink to the symbol of the Workers’ Party which brought them together.

She also wore a subtle red star for Lula’s inauguration in January — this time, on the soles of her strappy high heels.
