15 Diane Keaton-Inspired Mother-of-the-Bride Dresses

Diane Keaton is the mother-of-the-bride style inspiration you didn’t know you needed! While she often favors classic silhouettes (and lots of suits), her love of bold and glamorous details is what makes her the perfect person to turn to for a timeless yet fresh look.

From a turtleneck Ralph Lauren gown to a sequin Gucci suit, Keaton’s red carpet ensembles have garnered attention for decades due to her eye for unique and elegant fashion. And though she has a signature style of neutral tones and tailored garments, she still finds a way to step out of the box with her outfits, whether it’s with a spirited pattern or sequin embellishments. What we love most, however, is her ability to elevate a look with a statement accessory. Keaton often gravitates toward heeled boots, beaded jewelry, and vintage hats for a head-turning result that is easily replicable.

So, for mothers of the bride or groom who are in need of a few celeb-worthy wedding day pieces, we rounded up five of Diane Keaton’s best red carpet ensembles—plus, a few recommendations on how to recreate her looks yourself.

What Should the Mother of the Bride Wear to a Wedding?

Ieena for Mac Duggal Long Sleeve Tuxedo Gown

Keaton brought her signature style to the Ralph Lauren SS23 runway show in a menswear-inspired look by the fashion brand. She paired a black tuxedo coat with matching wide-leg trousers and a white button-down shirt. A round top hat and black rings completed this sophisticated yet stylish ensemble.

If you’re attending a black-tie wedding, consider this tuxedo gown from Mac Duggal. It incorporates the satin lapels and floor-grazing hemline of Keaton’s Ralph Lauren ensemble, in addition to a thigh-high slit and a draped bodice.

Best Midi: Amsale Mikado A-Line Midi Dress

At the 2004 Golden Globes, Keaton took a favorable fashion risk with this white ankle-length gown that featured a high collar, long sleeves, and a tulle underlay. She added an extra cool factor to the bold ensemble by accessorizing it with black sunglasses, white satin gloves, a long pearl necklace, and glitter stiletto boots. While mothers of the bride and groom should stay away from wearing white, if the couple has requested you wear this hue, this look will work for a more formal wedding.

Buy on Saks Fifth Avenue $695

Size: 2-16 | Materials: Mikado | Length: Midi

For a slightly shorter option, consider this midi dress from Amsale. It borrows elements from Keaton’s look—like the A-line silhouette and high neckline— but forgoes the sleeves, which makes it perfect for a summertime wedding. This sleek ensemble would also pair nicely with a sparkly shoe, like the stiletto boots Keaton wore on the red carpet.

Spring is in bloom with this gorgeous tulle number from Mac Duggal! Even though it opts for dainty floral embroidery instead of an oversized pattern, this dress will still make a statement at any springtime celebration due to its butterfly sleeves and pleated V-neckline.
