Catherine, who plays Eva Price in the ITV soap, wore a cream vintage Audrey Hepburn-style dress with printed red lips.
The actress looked simply stunning as she posed in her frock, which featured a full 1950s style flared skirt and high neck. Mum-of-one Catherine also proved that a little coordination goes a long way, as she teamed the retro number with red pointed heels.
Catherine's blonde locks draped over her shoulders and she kept make-up to a minimum, making her look chic, classy and elegant all rolled into one!
If you want your hands on it then you're in luck, as it's currently priced at £35 - reduced from £50 - on the retailer's website, Lady V London.
Catherine joined her Corrie co-stars Brooke Vincent and Katie McGlynn at the launch of the new American-themed restaurant, Infamous Diner, at the Northern Quarter.
Catherine is now back to work on Corrie after going on maternity leave. Eva was last seen on screens in February, where viewers saw her leave Weatherfield and boyfriend Jason Grimshaw behind after he wrongly accused her of having an affair with his dad Tony.
