Meghan Markle has said "yes" to a top secret dress designer!
In preparation for her upcoming royal wedding
with Prince Harry
this May, ET has learned that the 36-year-old actress has selected a designer with expert help from her close friend and stylist, Jessica Mulroney.
A source tells ET that Markle has even had her first fitting already! It took place at Kensington Palace last weekend, when Mulroney, who is originally from Toronto, was in town to help her pal with wedding planning.
So, what type of vibe is the former Suits
star going for on her special day? According to the source, don't expect anything too over the top.
Markle is aiming for "simple and elegant." And if her personal style
is any indication of how she'll look during her nuptials, we already know she'll look effortlessly stunning
The source also tells ET that Prince William, who is expected to serve as best man
, and Kate Middleton's two children, Prince George, 4, and Princess Charlotte, 2, will play a special role at the ceremony as page boy and flower girl.
As ET previously reported, Markle would also like both of her parents to be involved. The brunette beauty has already asked her father, Thomas, to walk her down the aisle.
"She does want him included and she wants to uphold tradition," an additional source explained last month.
