All of Duchess Kate's best wedding guest looks

When the guests at a wedding are high-profile enough, sometimes seeing their looks on the big day is just as exciting as seeing the bride! Case in point: Prince Harry and Meghan Markle's nuptials, where fans were equally excited to see what Duchess Kate donned for the festivities. The new mom has definitely established her feminine wedding style over the years, mostly in patterned dresses with pretty coats or silk numbers with blazers on top. Scroll through our photo gallery to see the Duchess's best wedding guest looks to date...

For her most high-profile wedding guest moment to date, at brother-in-law Prince Harry's nuptials to Meghan Markle in 2018, Kate opted for a familiar silhouette in the palest yellow Alexander McQueen coat dress. Just weeks after she welcomed Prince Louis, the duchess opted for a design very similar to the one she wore to Princess Charlotte's christening. She topped off the look with a floral-embellished Philip Treacy hat. (Charlotte, meanwhile, was also dressed to impress in a bespoke Givenchy dress, complete with pockets, and monogrammed Aquazzura shoes!)

At her sister Pippa Middleton's May 2017 wedding to James Matthews at St Mark's Church in Englefield, England, the Duchess of Cambridge played a supportive role rounding up the young attendants. The royal wore a pink dress by Alexander McQueen in a shade that matched the sashes on the sweet dresses worn by the flower girls, including Kate's daughter Princess Charlotte.

In May 2013, while pregnant with Prince George, Kate wore a fun polka-dot dress from Topshop and a black and white fascinator as her friends William van Cutsem and Rosie Ruck Keene tied the knot at the church of St Mary the Virgin in Ewelme near Oxford, England.

In October 2010, when Kate and Prince William attended Harry Meade and Rosie Bradford's nuptials at the Church of St. Peter and St. Paul in Cheltenham, the couple were keeping a secret – they were engaged! The future Duchess' blue Issa dress, worn with a black jacket and feathered hat, was in a similar shade, and by the same designer, as the now-iconic dress she would wear weeks later for the royal engagement announcement.

A summer coat worn over a ladylike dress is always a great option. Catherine, Duchess of Cambridge went for a natural look for the wedding of Emily McCorquodale and James Hutt at The Church of St Andrew and St Mary in Grantham, England in June 2012. The royal's floral-print Jenny Packham dress was topped with a linen coat by Katherine Hooker and a woven beret-style hat.

In the past, a day dress paired with a tailored jacket was Duchess Kate's go-to look for weddings. While a royal girlfriend, Kate opted for a silky violet frock and baby blue jacket to watch Lady Rose Windsor and George Gilman walk down the aisle at The Queen's Chapel, St James's Palace in July 2008.
