The Queen has given Meghan Markle her approval. But Pippa Middleton's upcoming wedding is going to be a huge test. She needs to be stylish but modest. Charming yet understated. The wedding will require a delicate balancing act, and Prince Harry knows that all too well.

Markle has already arrived in London ahead of Middleton and James Matthews’ wedding. She immediately went to Kensington Palace. This will be the first time Markle’s officially gone to an event with her boyfriend’s family. So this is an enormous step in their relationship.
