The former Suits Star opted for a custom-made pale pink Carolina Herrera dress on Saturday when she made her Trooping the Colour debut.
According to PEOPLE, the short sleeve dress marks a stray from tradition, as the ladies of the royal family typically opt for long sleeve options at the annual Trooping the Colour.
Meghan’s new sister-in-law, Kate Middleton, has always worn a sleeve that comes past the elbow since making her Trooping debut in 2011.
Princess Diana also never wore a short-sleeved look to the official celebration of the Queen’s birthday from her first appearance in 1981.
Though she’s only been a royal since her May 19 wedding to Prince Harry, breaking protocol is nothing new for Meghan.
She didn’t wear nude pantyhose to her engagement photo call in November, she went with her signature messy bun during numerous engagements (including her wedding) and she gave a 10-year-old girl an autograph during a visit to Cardiff Castle in Wales (a royal no-no!).
