Today International flavor
As Americans lust after exotic beaches, Africa becomes a place of swimsuit inspira-tion. "So many people have only negative connotations of the continent—blood diamonds, AIDS, famine," says Yodit Eklund, a 27-year-old designer who lived in six African nations as a child. "I wanted them to think about the beauty here." She launched Bantu in 2008. Prints inspired by traditional wax cloth fabrics are manufactured using local materials and labor, and are sold at high-end spots such as Barneys. (An online Bantu boutique opened this year.) Says Eklund, "I hope people are happy to wear something more meaningful than Billabong."
