Meghan Markle, 36, wore a green shift dress with a tied waist belt and no sleeves to join her fiance Prince Harry, 33, in an interview with the BBC.
The pretty dress was an instant hit with fashion fans and sold out in hours according to the brand Parosh.
During Meghan and Harry’s first joint appearance in front of the British press the brand posted on their Instagram account: “The bride-to-be wore our beautiful dress from fw 2017-18 Collection!”
They later added: “This dress is sold out but we are working hard to restock it ASAP”.
The brand has now revealed that they will be issuing the dress again, but they will name the gown after the actress, dubbing it “The Meghan”.
The dress, which costs a whopping £489 sold out in less than an hour, the founder of the Italian label Paolo Rossello revealed.
“It was totally insane, an amazing surprise,” he told the Telegraph, adding: “We were astonished to see Meghan with our bow detail dress. It was a dream.”
The 25-year-old brand which focuses on customised vintage gowns will have had an undeniable boost in popularity thanks to Meghan’s choice, if the Kate-effect is anything to go by.
Kate Middleton’s engagement dress was also incredibly popular and sold out within hours.
Rossello said: “It’s a Parosh iconic dress enriched with bow for this season, but suitable for any occasion. I thought Meghan looked very sophisticated matching it with high heeled shoes and white coat – it was very feminine.”
The brand states on its website that its designs are: “A combination of rich details creating modern, sophisticated garments, enhanced by a thousand shades of vintage and ethnic tones.”
Meghan’s white coat, which she was also seen wearing on Monday, was from a Canadian brand Line The Label cost £559.56 and sold out within minutes also.
The actress accessorised with a pair of 18-karat yellow gold and opal earrings by Canadian brand Birks and priced at £850. She added a pair of £550 Aquazzura shoes.
This takes the beaming bride-to-be’s ensemble to a total price of £1598.56 – not including her whopper of an engagement ring.
What was Meghan Markle’s engagement ring like? The ring was revealed on Monday when the pair attended a photocall.
It was revealed that Meghan’s ring was designed by Prince Harry and featured a huge diamond from Botswana.
It then had outside stones from the personal collection of Prince Harry’s mother set in a band of gold.
Botswana is special to both Harry and Meghan, as their pair spent a three week holiday there.
