Queen Charlotte looks ridiculous!
Please take note that for now, I'm ignoring the subject on her being black, considering many people have already covered it.
No Queen in her right mind would wear clothing 40 years out of date with the rest of the population. Queens like her would have been wearing the latest fashions for both the English and French, most notably Parisian fashions mixed with a bit of English flavor, as well as her own personal preferences, to go with the country she rules.
Even stupider, Frock Flicks pointed out that Regency England in real life really did have some weird fashions at court during this time period, and the designers didn't even use it!

They were too obsessed with making her look like some kind of bizarre, 18th century version of Beyonce, complete with wigs that looked like nuclear mushroom clouds on her head.
