You can view Rihanna in her cool & comfy oversized print sweatshirt here.
You can buy Rihanna's sweatshirt here from the Browns website or here from the US based Brian Lichtenberg website.
I have blogged about Rihanna's sweatshirt before, when Miley Cyrus & Alexandra Burke wore it in charcoal grey & orange respectively, and you can view those posts here and here.
