Stacks of freebie designer clothes poured in when Meghan Markle started dating Prince Harry — and the future duchess had furious fights with palace aides who sent them all back, according to a new report.

Keeping the free designer fashions sent by major labels is fine for an actress — but it’s against royal protocol, sources told the Sun.

Markle was livid when told she couldn’t keep the duds, which were sent to her at Kensington Palace after news broke that she was Prince Harry’s girlfriend, the Sun reported.

News of the high-fashion tantrum is just the latest accusation of bullying to flood the gossip pages in the days before her and Harry’s much-anticipated interview with Oprah Winfrey on Sunday.

“As an actress it was perfectly acceptable to take freebies sent by fashion chains and designer labels,” one source told the UK paper.

“But Meghan had to be told it was not the done thing when you are a member of the royal family.”

Prince Charles eventually picked up the tab for Markle’s wardrobe expenses after she married Harry in May 2018.

Buckingham Palace is launching a probe into the bullying allegations, which Markle has countered are just a “calculated smear campaign” orchestrated by the palace to deflect attention from the Winfrey sit-down.
