Chanel Iman takes a trip to tropical forests for Rosa Cha’s most recent advertising campaign. Last time we saw the American beauty, she was wearing fall fashions in an Elle Italia shoot, and now she looks ready for warmer weather in the Brazilian label’s spring 2011 campaign. Photographed by Gui Paganini and with retouching by Alex Wink of Studio AW, Chanel dons the label’s colorful swimsuits, casual wear and lingerie.
