Known for her deep understanding of royal customs, including some that are not officially recorded, the Princess of Wales established herself early in her public life. When she married Prince William in a lavish ceremony at Westminster Abbey in 2011, she chose a Sarah Burton for Alexander McQueen wedding dress that held special significance.

According to style expert Miranda Holder, the choice of this designer was deliberate; it showcased both the beauty of craftsmanship and the traditional techniques involved in creating such garments. It is worth noting that the cost of the wedding dress was paid for by Kate's parents. Holder stressed that royal attire often has a deeper meaning, acting as a family tradition.

A family heirloom, a political statement, or part of a larger PR strategy. However, for her second dress, Kate had the opportunity to express herself more freely. This outfit was also designed by Alexander McQueen but was more casual and included a lovely cardigan.

This option allows more reserved brides to express themselves and their personal style, especially in a more intimate setting with only 300 guests in attendance. Holder points out that for the reception, after the formal ceremony and photo ops, Kate made a striking change by lengthening the hem of her dress and removing the elaborate train, allowing her to show off a more relaxed yet elegant style at the ceremony.
