Rachel McAdams
How can you possibly not recall the actress who played Regina George in Mean Girls? Aside from that, Rachael McAdams also worked on The Notebook, The Vow, and The Time Traveler’s Wife. This star wore a red sheer dress by Marchesa to the Cannes Film Festival in 2011. She looked ravishing when she arrived at the premiere of Midnight In Paris, in which she had a starring role. She decided to forgo fancy jewelry and let the dress be the main focus.
