While her appearance was breathtaking, per usual, Meghan (seemingly) unknowingly bared her nipples through her dress.
Markle and Prince Harry were all smiles as they laughed and cuddled up to each other.
On Thursday, just a few days after the cookbook project was unveiled, Meghan hosted her first royal event at Kensington Palace to celebrate its launch.
Meghan also met with the curators and artists as well as descendants linked to the works displayed and watched a short performance from Ngāti Rānana, a Māori cultural group.
Earlier, when Meghan first arrived she practised her hongi when she was shown a large artwork by four female New Zealand women - a blue tarpaulin woven into a large cloth that symbolised a rising wave.
The silk gown, designed by Clare Waight Keller for Givenchy, features a boat neckline and a sculpted waist.
A recent clip was also shared of Prince Harry revealing that he "still panics" when he sees the Queen.
However, she didn't reveal what she chose for her something borrowed, something old and something new, although there's no doubting that they would have been just as sentimental.
