But there will likely also be a tinge of sadness that Harry’s late mother, Princess Diana won’t be there to see her youngest son tie the knot.
That’s why the couple are planning to pay homage to the groom’s mother, in some sweet yet subtle nods to honour her memory.
We already know certain touching decisions Harry and Meghan have made to incorporate Harry’s late mother Princess Diana into the day.
Like choosing Sir Elton John to perform at the wedding.
Elton – who was already on the guest list to the wedding – is a fitting choice due to his history with Harry’s mother.
Elton and Princess Diana were close friends during her life and the two worked together to raise money for AIDS research and awareness of the disease.
He famously sang “Candle in the Wind” in a heart-wrenching tribute to Diana at her funeral in 1997.
Meghan is also expected to have given a nod to her late mother-in-law in her choice of bouquet, a mix of locally sourced white garden roses, peonies and foxgloves.
“The white garden roses are a considered ode to Harry’s mother Princess Diana – they’re widely known to be her favourite stem and have no doubt been sourced from the royals own Crown Estate and Windsor Great Park,” explains Lana Elie, CEO and Founder of online flower market, Floom.
“They’re were also found blooming in Diana’s White Garden at Kensington Palace last year (temporarily erected to commentate the twentieth anniversary of her passing).”
Wedding planner Lisa Johnson from Carmela Weddings expects there will be other subtle yet significant tributes on the day.
“They will go much further than a simple mention in the wedding speech and a member of the Spencer family thought to be giving a reading,” she says.
“I’m expecting to see a significant amount of thought bringing Princes Diana into the ceremony, with many subtle loving nods to remember her by.
“From the flowers to the diamonds that Meghan will be wearing and which are anticipated to be from Diana’s personal collection, I think that these not-so-obvious ways are the perfect touch to bring the memory of a lost family member back into a couple’s big day.”
Another potential tribute to Princess Diana could have come in the charities chosen to benefit from Harry and Meghan’s wedding gift fund.
The couple have said that instead of gifts they would like people to donate to seven charities of their choice.
These include The Children’s HIV Association, which supports children growing up with HIV across the U.K. and Ireland, and Princess Diana’s was known to be a keen supporter of HIV/AIDS charities.
Of course Meghan is already has a special piece of jewellery with a significant connection to Harry’s late mother – her engagement ring.
The central diamond is from Botswana, the smaller two stones either side are from Diana’s personal collection.
“To make sure she’s with us on this crazy journey together,” Harry explained during their engagement interview.
While Meghan added: “Not being able to meet his mum, it’s so important to me, to know that she is a part of this with us.”
According to Lisa Johnson when paying tribute to a lost loved one at a wedding, it’s a good idea to strike a balance between subtlety and sentimentality.
“Whilst the weddings I plan are very individual to that couple, I often get asked how to adapt them to remember a loved one,” she says.
“I often recommend one or two low-key ways to bring the memory of that person back but advise not to let it overpower their own day.”
Here’s some suggestions of how to pay tribute to a lost loved-one on your big day:
Aside from her engagement ring Meghan could be gifted another piece of jewellery from Diana’s personal collection to mark the special day. “Whether it’s a locket with a photo, a pair of earrings, or a ring, it’s a touching tribute to that person and makes them a part of the big day,” explains Lisa.
Candles can act as a touching reminder of a lost relative or friend. “Consider a beautifully-styled table with candles for the evening, where guest can light a candle in memory of someone who is forever in their hearts,” Lisa suggests.
Photo tables or boards
“Whilst our clients love every aspect of their wedding day to be styled to perfection, a simple photo table or photo board is a touching way of bringing back happy memories,” Lisa explains.
“Whether a loved one had a favourite sweet or savoury treat, why not incorporate this into the day, perhaps through favours, with a special note of remembrance about that person,” Lisa suggests.
No doubt there will be a toast to Princess Diana and other late loved-ones on Harry and Meghan’s big day. “Simple and effective, especially when combined with a moment of silence, it can be a powerful way to bring back the memory of a loved one for a shared moment in time,” explains Lisa.
We already know that Sir Elton John will be performing, and including some favourite songs into the playlist is a great way of playing tribute. “Celebrate that special person’s life by inviting everyone on to the dance floor for his/her favourite song. This can be an uplifting way to remember that person,” Lisa says.
