We only got a teeny little peek of the hunter green P.A.R.O.S.H dress during Meghan Markle and Prince Harry's engagement photo shoot but that didn't stop royal obsessors from snatching it up in record time.
A rep for the Italian designer said they had no idea the royal-to-be chose their brand for the big day, and the company was absolutely thrilled, telling us the news was a "super surprise!"
Markle has already one-upped her future sister-in-law, because Kate Middleton's famous engagement dress didn't sell out for 24 hours. Markle's was out of stock in about an hour.
We're told even though the chic green dress sold out so quickly, the company is already working on re-stocking the coveted item.
P.A.R.O.S.H. says "We are very excited... [trying] to understand how we could ever thank Meghan!"
We're told the company is even tossing around the idea of naming the dress after Markle.
