Meghan reveals meaning of the something blue sewn into her givenchy wedding dress
I'm not aware of any information that suggests Meghan Markle, the Duchess of Sussex, has revealed the meaning of the "something blue" sewn into her Givenchy wedding dress. The "something blue" is a traditional element of a wedding dress, and it's often a small token or charm that is sewn into the dress as a good luck charm.
Givenchy, the fashion house that designed Meghan's wedding dress, has not publicly disclosed the meaning or significance of the "something blue" in the dress. It's possible that Meghan may have shared the meaning with someone close to her, but it has not been publicly disclosed.
It's worth noting that Meghan's wedding dress was a bespoke design created specifically for her by Clare Waight Keller, the artistic director of Givenchy. The dress was a stunning white silk gown with a flowing train and a subtle nod to the British royal family's tradition of wearing white wedding dresses.
