And while they aren't technically family yet, they are already one step ahead because they're already wearing the same clothes. Markle and Middleton each have distinct style sensibilities but every so often they overlap in an obvious way.
Take, for example, Middleton's famed sapphire engagement dress. The V-neck dress in a distinct color has a double in Markle's own closet. Markle has worn the same colored dress with the same neckline and her hair styled the same way as Middleton's, and this wasn't the only time this happened.
Scroll through our 13 favorite style twinning moments of Markle and Middleton's, and celebrate their new family in a fashion-forward way.
1. SIMILARLY CUT RED A-LINE DRESSES
The red hot color isn't the only similarity between these looks. The dress waists are cut in the same place, they lack sleeves, and they're paired with simple pointed pumps.
2. GEOMETRIC SKIRTS
What better way to add pizazz to a white top than with a geometric colorful skirt?
3. BLUE V-NECK BUTTON DOWN LOOKS
Both accessorized with clutch bags and pointed heels, naturally.

They even wore their dresses with the similar footwear.

Each dress is different, but they share unique similarities, like the see-through sleeves and peekaboo cutout lace patterns.
7. MIDIDRESSES WITH SIMPLE HEELS
Even their bracelet jewelry is pretty much the same.
8. LACE NECKLINES
If you photographed both dresses from the waist up, they'd be the exact same minus a very slight hue difference.

Black strapless gown? Check. Simple nails? Check. Statement necklace? Also check.
10. NAVY BUTTON MIDISKIRTS
While they styled their gold button-covered navy midiskirts differently, the skirts themselves are a dupe for one another.
11. ALL WHITE EVERYTHING
Markle and Middleton certainly have their own unique spins on the all-white trend, but they looked strikingly similar nonetheless.
12. HATS OFF!
A simple hat with a white shirt can create an über casual look, just as these future sisters-in-law demonstrated.
