Duchess of Sussex's 'matchmaker' and friend Misha Nonoo advertises her label's 'Husband' blouse as the 'shirt that sealed the deal'

Meghan famously wore 'The Husband Shirt' by Misha Nonoo at her first public appearance with Harry - and now it appears her fashion designer friend behind the brand is cashing in on the royal connection.

A sponsored post from Misha Nonoo that has been circulating on Instagram describes the $185 (£138) white blouse as 'the shirt that sealed the deal'.

Meghan, 36, wore the simple white shirt with ripped jeans when she attended the Invictus Games with Harry in Toronto last September - just two months before their engagement was announced.

Although surprising given her closeness to the bride, Misha's brand is far from the first to seize on the marketing potential of a link to the royal romance.

Jessica Alba promoted her natural products business The Honest Company after it was revealed that Daniel Martin, one of her consultants, was doing Meghan's make-up - while make-up artist Charlotte Tilbury shared the products used by wedding guests Amal Clooney and Kitty Spencer on the big day. 

Misha, who is rumoured to be the matchmaker that set Harry and Meghan up on the blind date that sparked their fairytale romance, attended the royal wedding in Windsor on Saturday, posting several snaps of Instagram from the big day.

It has raised eyebrows among some observers, who suggested she's using her connection to Meghan to market the shirt famously worn by the new Duchess of Sussex.
