Kate looked mesmerising in an altered £3,893 Jenny Packham dress.
Some royal fans thought this dress was Kate sending a message through her clothing to Meghan Markle, who spent the weekend in New York attending the Global Citizen Love concert with her husband, Prince Harry.
The Princess, who appeared to come out with this dress all guns blazing, showed to royal fans that she still has the ability to wow the crowds with her style.
Melita Latham, a clothing designer and founder of Melita Latham London, spoke to Express.co.uk about Kate sending messages to Meghan with her Hollywood attire.
