Rachel: Lady in Red

It’s a hard choice to make but which hot actresses looked better in their trompe l’oeil red dress: Rachel McAdams or Blake Lively?

Rachel left the crowds at Cannes speechless when she showed up to the premiere of Midnight in Paris while wearing a red and beige gown that made it look as if she was wearing a see-through dress. (Don’t worry, Rachel was totally covered – no wardrobe malfunctions here!) Rachel topped off the look with Casadei satin pumps which helped elongate her gorgeous legs.

Rachel’s beautiful gown looked very similar to the red Marchesa minidress that fashionista Blake wore to CinemaCon earlier this year. Check out pics of Blake’s dress after the jump.

While the two dresses are very similar they also create completely different looks: Blake looks youthful and girly while Rachel looks glamorous and elegant.

The see-through look has been very popular on the red carpet this year. Rihanna embraced the trend at the Grammys when she wore a white trompe l’oeil Jean Paul Gaultier dress. The “Rude Boy” singer also wore a similar see-through black lace Stella McCartney dress to the Met Gala earlier this month.

So, who looks better in red and beige: Blake or Rachel? Vote in our poll and play fashion critic in the comments.
