At the 2011 Brit Awards earlier this year, Rihanna wowed the audience when she wore this stunning Oscar de la Renta Spring 2011 creation.

The beautiful singer dazzled in the strapless ivory silk gazar gown embroidered with red carnations, which complemented her fiery red hair perfectly.

Since the gown is such a standout piece, Rihanna chose not to overwhelm it with any accessories.

J.K. Rowling wore a green and rose pink version of the gown (which doesn’t have the same cinched in waist) to the World Premiere of “Harry Potter and The Deathly Hallows: Part 2″ in London recently.

The author played up the elegance of the dress by accessorizing with some pretty pink pieces including floral Bulgari earrings, a textured clutch and a matching pink diamond cocktail ring.

She opted to wear her hair in a chic up-do and also wear matching baby pink nail polish.

It’s hard to pick a winner for this one since both women styled the dress so differently, but my vote is going to Rihanna.

She looks amazing when she wears anything red and brings out the boldness of her hair colour even more and I much prefer the colour combination of her dress to the one worn by J.K. Rowling.
