8 year old girls dress for coronation

[IncessantNameChanger]

I'm looking for a coronation themed dress for my 8 year old daughter. There was lots of union jack / crown / corgi etc dresses for the jubilee but nothing so for for the coronation? I made a dress for the jubilee and it was hideous. Ideally a tshirt type pull on dress. I have just bought this one but it's not quite what I'm after. Thanks

Not sure if this might do? Goes up to age 9-10, UK sizing.
It's not a t-shirt dress, though!
