Kind of suspecting this bit is true but they're missing the context - the earlier stories were all about the tights/shoes and Kate crying and supposedly happened in front of others. And we're now told the dresses only arrived 4 days before. So is it more like:
Round 1
"Everything will be here 4 days before wedding, shoes dress etc"
"Have you got tights"
"No no no tights bla bla"
"New shoes arriving few days before, won't be broken in...plus protocol y'know..."
Meghan snaps something about not wanting fuddy duddy tights, Charlotte being a baby, whatever it is. Kate cries
Round 2
Bridesmaids dresses turn up, don't fit. Kate already annoyed, realises Charlotte's dress is beyond a few alterations. Nippy texts ensue, Meghan cries
Round 3
Kate takes flowers, Meghan throws in bin.
Round 4
Baby brain comment
That sort of scenario would fit with what everyone has said - stories from 3rd parties, Harry, finding freedom, spare. Kind of thinking that they all have at least an element of truth.
Bunch of petty wedding stress which should have been forgotten and consigned to history, not rehashed 5 years later
