Author J.K. Rowling looked gorgeous in a gardenesque Oscar de la Renta gown recently at the "Harry Potter and the Deathly Hallows Part 2" premiere.

If you recall, Rihanna was the first to prove a budding beauty in a red and white version of the same floral gown while performing at the 2011 Brit Awards back in February.

While both ladies did a great job of choosing the perfect color scheme for their individual hair and skin types, I tend to prefer the sharp contrast of the red roses against the white backdrop as modeled by Rihanna. It just oozes romance!

Which style is the right way, and which one needs to hit the highway? You tell me in the comment section below.
