Her burgundy pleated dress.
The Suits actress was wearing the Wilfred Beaune Dress from US brand Aritzia and it's surprisingly affordable -
well, as far as Royal outfits go.
The dress retails for about AUD$233.
Markle completed her look in this year's biggest styling trend of tonal blocking with a leather jacket and clutch in the same tone (geddit?)
With thin straps, a wrap waist and a floaty pleated skirt, it's the perfect summer dress that can do a Christmas function just as well as a weekend BBQ.
Just quietly, it's a great option for a wedding too, either as a guest or even for bridesmaids.

Unfortunately, the burgundy version of Markle's dress is currently out of stock BUT there are plenty of other options to choose from.
'Foulard' is a beautiful dusty-pink-purple while the black and 'kinetic' (grey) versions would serve you year after year.
Get in quick though - you can bet now it's got Meghan Markle's seal of approval, it won't remain in stock for long.
And if the engagement rumours are anything to go by, we could see Meghan sparking her own 'Kate effect' like her potential sister-in-law the Duchess of Cambridge.
It might not win you Prince Harry's heart, but it will get you lots of compliments.
