Wickstead triggered a social media storm after she reportedly tweeted: 'Her dress is identical to one of our dresses. Apparently a lot of commentators were saying, 'It's an Emilia Wickstead dress'.'
She continued: 'Her dress is identical to one of our dresses. Apparently a lot of commentators were saying, 'It's an Emilia Wickstead dress'.'
The British-based designer then went on to take a swipe at Meghan's wedding day look.
She wrote: 'If you choose a simple design the fit should be perfect. Her wedding dress was quite loose.'
Emilia also commented on Meghan's hair and makeup, saying: 'I was like, 'Hold the wisps [of her hair] back — it's a Royal Wedding for God's sake.'
Social media users were not happy with Wickstead's comments.
One wrote, '#EmiliaWickstead has a lot of nerve talking rudely about the #DuchessOfSussex’s wedding dress! Emilia actually works as a designer for the royal family!! Highly unprofessional!'
Another added, 'Emilia Wickstead is a very successful designer. She has dressed the Duchess of Cambridge on more than one occasion. It's a shame that she has elected this forum to voice her complaints concerning the dress origin. Why wouldn’t she have went straight to Givenchy?'
'Deeply unprofessional comments from Emilia Wickstead on Meghan’s Givenchy gown! Will Kate Middleton sever ties with one of her favourite designers over this?'
The royal family is yet to respond to Wickstead's comments.
