Moore stunned in a sparkly crop top, which she styled with a matching high-waisted pleated skirt, bright orange pointy-toe heels and black hipster glasses. The designer looked just as dapper, donning a burnt orange suit with a purple tie, as they posed for a photo together.

Her three daughters -- Rumer, 27, Scout, 24, and Tallulah, 22 -- were also in attendance, and apparently thought their mom's striking look was just as cool.

Tallulah later took to Instagram to share a close-up pic of her mom sporting the oversized glasses and midriff-baring top.

"Mom is literal teenager," she captioned it.

This, of course, isn't the first time the Forsaken actress has proved she's as fabulous as ever. Earlier this month, Moore dressed to impress in a black mini dress that showed off her toned legs while attending the Saint Laurent show at The Hollywood Palladium with her two youngest daughters.

And let's not forget that time her abs were on full display in another one of Tallulah's Instagram snaps.
