In Narciso Rodriguez - Greta Gerwig.

Walking the red carpet at the Arthur Premiere in Narciso Rodriguez was Greta, who channelled old Hollywood charm.

Her White and Black dress had a high waisted skirt with a belted accent and sheer details on top. She styled the dress to perfection with a wavy hair do' and red lips.

Greta carried a Cecilia clutch and paired it with Christian Louboutin Très Décolleté pumps.
