You probably could have guessed that Rihanna doesn't spend her Saturdays running errands in t-shirts and jeans — and if she does, those t-shirts and jeans are a little more fashion-conscious than most. But her weekend traveling in London and Monte Carlo meant another lineup of bold street style (and there wasn't a pair of jeans or a basic tee in sight).

In London, the singer added a sleek white crop top to a leather skirt and suspenders, then finished it off with black high-tops, shades, and a beanie. For her outings in Monaco, Rihanna embraced a high-fashion dress code, slipping into a head-to-toe printed Givenchy ensemble for a little shopping. For another Monte Carlo outing, Rihanna may have forgotten her pants, but she certainly made up for the lack of clothing with ample accessories: she completed her bodysuit and semisheer top with a sleek clutch, sunglasses, and strappy flat sandals. Give all the ensembles a look, then decide: which of Rihanna's weekend styles rules?
