When asked about the attention she received, Pippa revealed she found it "embarrassing, definitely."
"It was completely unexpected," she said. "You know, I think the plan was not really for it to be a significant dress. Really just to sort of blend in with the train."Those hopes of "blend[ing] in" didn't quite happen...
"It's actually still in my wardrobe at home," she said. "I haven't worn it since. But I think I'll just keep it there...I think it's the sort of thing that I'm sure I'll bring out if someone wanted to see it or my children one day want to see it. Then I'll show them."
And is she planning to follow in Kate's footsteps and start a family in the future? It sounds like a baby could be on the cards.
Pippa described Prince George as "amazing" and said, "He's a very dear boy...he's brought a lot of pleasure and fun for all of us, the whole family.
"I love children and babies. So I would happily have one."
