Keira Knightley and boyfriend Rupert Friend made a rare appearance out in London this week to attend the screening of her new short film, but long titled “The Continuing and Lamentable Saga of the Suicide Brothers.”

The star wore a navy blue sleeveless Erdem Resort 2010 maxi dress with a interesting print which includes butterflies.

Keira was one of the first to bring Erdem to the red carpet, so it’s nice to see she has remained loyal to the brand.

Erdem Moralioglu is celebrated for for his unique take on elegant prints and colour. I really wish we will see more of his brilliant work on the red carpet.
