The actress bit back her smile while walking the black carpet at the IFP, Calvin Klein Collection, and Euphoria Calvin Klein Women in Film celebration at Cannes on Thursday night.
The VAST majority of Rooney's past looks have been either black or white, or, in some cases, both, but this time we got to see her change it up ever so slightly.
She went nude!
Roons chose a delicate slip of a dress by the designer for the event, styling it with t-strap heels and tight bun.
Though pretty and ethereal, it's also rather forgettable.
We hope she wears something a bit more exciting next time!
