Why not bring your mom to the party?

That's what Katie Holmes did this week in New York, where she arrived with her super cute mom Kathleen at a party in celebration of Ava DuVernay, OWN, and Queen Sugar. For the garden party, Holmes—whose daughter Suri Cruise impressed us in a $1,200 dress at a gala—kept it spring-summer appropriate in a long-sleeve floral blouse with high-waist pants, while Kathleen kept it casual in a white, oversize shirt and jeans. DuVernay was, of course, on hand for a performance by Meshell Ndegeocello, and Pat and Anna Cleveland were among guests.

Later, Dior celebrated its upcoming cruise 2019 show with a welcome dinner at a pop-up bistro named Chez Christian, where celebrities like Paris Jackson and Stranger Things stars Charlie Heaton and Natalia Dyer dressed up in nothing but the French fashion house's designs.
