RiRi’s back onstage!

After over a month off, Rihanna returned to performing duties at the Formula 1 post-race concert in Singapore on Sunday.

Amidst some arm-flailing and crotch-grabbing, the 25-year-old showed off her round frame Depuis 1924 sunnies designed by Jean Paul Gaultier and a print t-shirt dress from Raf Simons‘ S/S 2014 menswear line!

Princess RiRi also threw on some fishnet tights that cut off at the knee and a white pair of her fave Comme des Garcons sneakers.

She just loves appropriating looks from the menz, doesn’t she?
