Because when you think about it, it's highly unlikely the former actress and soon-to-be Duchess will wear something similar to a gown she will have already been fawned over in, when she could wear absolutely anything else she wants, right?
Which is unfortunate really, because in the series seven finale of Meghan's hit TV show Suits - the episode which sees her character Rachel Zane walk down the aisle with fiancé Mike Ross - she looks incredible.
Wearing a princess style ball gown with lavish tulle train adorned with pearl embellishments and pretty lace applique, the dress suited the bride down to a T.
Meghan's character Rachel wore her long dark locks straight and loose, drawing attention to a skinny black ribbon around her waist.
The detail was in the back however, which featured a beautiful and subtle sheer fabric, allowing the gown to sit low but still providing a bit of coverage. The look was completed with a simple pair of elegant pearl stud earrings.
Meghan reportedly chose Rachel's wedding dress with the help of close friend, bridal stylist (and unofficial royal wedding planner) Jessica Mulroney who, due to her experience with bridal through working at famed wedding dress boutique Kleinfields, was well equipped to make sure the fictional bride looked the part.
And indeed it's hoped she'll do the same for the royal bride in real life for the big day in May.
When word got out in January that the bride had chosen her designer, it was reportedly with the help of stylist Jessica.
"Meghan flew in her close friend and bridal stylist Jessica Mulroney from Toronto to London last weekend where she attended a top-secret fitting at Kensington Palace with the designer," London-based royal reporter Omid Scobie told ABC at the time.
For their big day Meghan and Harry have chosen Alexi Lubomirski as their wedding photographer, the man behind the lens of their now iconic engagement pics.
And if Meghan's choice of gown for those photos are an insight into how the bride-to-be is sartorially swaying at the moment, she feeling a little more daring than her Suits character.
The £50K black tulle couture gown Meghan wore for the official shoot was by British designers Ralph & Russo.
It was from the designer's Autumn/Winter 16/17 collection, and featured a silk organza skirt, hand appliquéd with silk tulle ruffles and a long-sleeved sheer bodice embroidered with gold feather thread-work.
The bride will reportedly wear two different dresses on the day. One for the formal ceremony, and another more informal style for the reception at Frogmore House later in the day.
