Rihanna stunned on the streets of Brazil during the last few games of the World Cup last week, stepping out in several super fashionable styles. One of the looks RiRi rocked was a black jumpsuit with a jean jacket, Manolo heels and a pop-of-red lipstick. It's a perfectly simple yet chic style for a summer night, and she wore it flawlessly--Mostly because it's an easy outfit you can't really mess up.
