Bringing dainty back! Emmy Rossum makes them green

She can always be counted on to bring some much-needed glamour to the red-carpet.
And while many guests at Justin Timberlake's The 20/20 Experience album release party on Monday night opted for more casual trouser and jacket ensembles, Emmy Rossum made them all green with envy in her pretty embroidered dress.
The Shameless star was dainty in her demure cream frock featuring an intricate emerald floral design as she made her appearance at the event inside the El Rey Theatre in Los Angeles.
