Fame Pictures; INFdaily.comSweatshirt dresses can be seriously stylish.
Just ask Kelly Osbourne and Rihanna, who both wore this gray Marc Jacobs number recently.
Kelly chose the cozy-chic creation during her Dancing With the Stars downtime, wearing it while shopping with her mom on Robertson Boulevard.
RiRi opted for the oversize-sleeved outfit for a flight to Berlin.
But the ladies managed to make the same dress into totally different ensembles with their accessories...
Rihanna opted for a looser fit and added fierce Louboutin leopard-print boots, bracelets and a military-inspired hat, plus red lips.
Kelly glammed hers up with a belt, peep-toe pumps and a big pair of sunglasses.
