Sienna Miller's Bridesmaid Dress Is Going to Set the Trend for 2023

Of all the stylish weddings in 2022, it was of course no surprise to discover just how incredibly chic and beautiful the nuptials of fashion designer Savannah Miller and aristocrat James Whewell were last week. Located at the very romantic and bohemian Petersham Nurseries in Richmond (a well-loved fashion editor haunt), it was everything you want a Christmas wedding to be and captured in all its glory by the highly sought-after wedding photographer, Benjamin Wheeler

Millers's dress was custom-made by her team at Savannah Miller Bridal.

Cosy, twinkling with lights and candles, featuring rich, sumptuous fabrics for all of the outfits, and a winter wonderland-worthy setting to dine in… the entire vision was nothing short of an enchanted fairytale. Naturally, Miller looked like a storybook princess with her little Tilly Thomas tiara atop her tousled bob (by hair stylist Jordan Garrett).

Miller's dramatic cape cements the trend for 2023 brides.

Custom-made by Miller's eponymous label, Savannah Miller Bridal, her intricate wedding gown featured a bodice and scalloped neckline trimmed in fine gold beads and with a golden lace overlay. The outer lace layer appears to have then be removed post-ceremony to reveal the satin dress underneath, styled with a shimmering cape for those colder moments. With its costume-like details this a bridal look fit for the most decadent of period films, only thanks to beautifully natural makeup from star artist Wendy Rowe, the overall feel was entirely modern.

The after-party look featured the same bodiced dress minus the lace layer.

As to be expected, the guests and bridesmaids looked equally fabulous, and we couldn't help but immediately in love with the dusky-blue velvet slip dress that her sister Sienna Miller wore for the big day. It was simple and understated, a classic shade for a bridesmaid and although perfect for a winter wedding this is a hue that can easily work for any other time of the year. The bespoke Cerise dress is based upon a style that Sienna has reportedly always loved.

Combined with sparkly platform heels the look was suitably festive and joyful while remaining elegant and low-key. Miller also had a fluffy shearling jacket that she wore over the dress when the wedding party was outside—the very same jacket we only just documented from a look the actress wore on a night out in London earlier this week.

Miller kept things ultra-simple in terms of styling.

Earlier in the year we began to see the slip dress as a serious contender for wedding guests when multiple celebrities, including Victoria Beckham, wore silk-satin versions to the wedding of Brooklyn Beckham and Nicole Peltz. The interest was so high that a few months later the brand released a limited edition run of the metallic gowns to satisfy demand.

With two such high profile endorsements of this '90s dress trend, I expect to see many a slip dress sold in 2023 for wedding guests and bridesmaids. Although the Miller sisters' creations are custom-made you can enquire via Savannah Miller Bridal for your own. I have also provided some similar slip dress styles below to peruse. Just add heels and enjoy!
