The account posted an image of Meghan in it, with the captioned: "So honoured to have HRH Duchess of Sussex in our Autumn '19 coat at Remembrance Day service. x Stella."
The post had received more than 44,000 'likes' with several people complimenting it, but she was forced to delete the post after it sparked a furious backlash from social media users, who labelled the post "insensitive", "inappropriate" and "tacky".
One person wrote: "Remembrance day is to honour those who fought for us not to use for advertising purposes. Pretty shocked."
Another commented: "Today is about those who gave their lives for our freedom. Who gives a f**k what she's wearing."
A third shared: "Totally inappropriate."
One added: "Slightly inappropriate to advertise your clothes worn at the memorial service."
