As an actress on the hit show We Were Liars, Mamie Gummer gets to hide things for a living. As a front-row guest at Celine’s winter 2026 show, the 42-year-old actress has to be a little more transparent—especially since she’s on Get Ready With Me duty for ELLE, giving us an unfiltered look at her Paris Fashion Week adventure.
Dressing up comes naturally to the Connecticut native, who had a treasure chest in her childhood playroom stuffed with her mother’s (Meryl Streep’s) old movie costumes and wigs. Gummer began performing Off-Broadway just after graduating from Northwestern University and earned her first Drama Desk nomination in 2016. Around that time, she shot an H&M campaign with her sisters, Louisa Jacobson, now the star of The Gilded Age, and Grace Gummer, who’s currently appearing as Caroline Kennedy in Love Story. (But you already knew that.)
On We Were Liars, the eldest Gummer wears long, ribbed Rachel Comey sweaters and metallic Jason Wu dresses as a kind of soft armor as she fights with her sisters for love and, more so, for money. In real life, Gummer and her stylist, Chloe Hartstein, stick with floor-length monochrome looks in butter yellow or molten silver from Adam Lippes and Simkhai.
When we tagged along with Gummer to Michael Rider’s latest collection for Celine in Paris, there was a flood of options to back up the cool-but-not-fussy vibe that Gummer seems to have on lock, including a deep purple trench coat, a boatneck black dress embossed with silver roses, and a pile of thin, layer-worthy turtlenecks.
Here’s how the actress prepped for the show, crêpes included.
Don’t overthink it—a crêpe is a pancake.
Dear reader: Lucky us! This is my good side.
“Mamie Gummer.” Crazy name, non? I still sometimes read it as a typo.
Nothing gets between me and my Celines.
“Bag-uette.”
“En route.” That’s French for “not late yet.”
“ON Y VA!” (Also happens to be the name of my seventh grade French textbook…)
Anyone else remember the end of A Streetcar Named Desire?
Showtime, Gamie Mummer!
