Donning gorgeous duds from Stella McCartney, Louis Vuitton and Chloé, the 30-year-old actress posed for the David Slijper front page shoot and chatted about everything from her body to giving birth.
A few highlights from Miss Miller's interview are as follows. For more, be sure to pay a visit to Harper's Bazaar UK!
On giving birth:
"It's the best, the greatest thing in the world. I would do that day a million times again. I would do that day, every day. I loved it."
On hiring a nanny:
"It's been just the three of us, which was amazing, and exhausting. We are going to get a nanny, but it felt important to first learn for myself who I was as a parent."
On loving her post-pregnancy body:
"My body's a completely different thing to me, it's not mine—all the attachment to its flaws or any aesthetic attachment is gone. You understand what breasts are for; and I have such enormous respect for my body because of what it can do."
