Rihanna may have been the guest of honor at Stella McCartney‘s evening wear presentation on Saturday night, but that didn’t stop her from wearing this slinky little number by Giorgio Armani.
Her forest green gown is almost identical to the one she wore to the Grammys last weekend, but it still the same amount of sex appeal.
Which gown do U prefer? Black or green???
