She's launching an important new initiative promoting children's mental health.

The day has finally come for the Duchess of Cambridge to guest edit The Huffington Post UK -- and unsurprisingly, she's doing it in style.

Kate kicked off the day with a blog post launching a new initiative called "Young Minds Matter," and will spend the remainder of her editing stint concentrating on children's mental health.

"The mental health of our children must be seen as every bit as important as their physical health," she wrote. "For too long we have been embarrassed to admit when our children need emotional or psychiatric help, worried that the stigma associated with these problems would be detrimental to their futures."

For more about Kate's guest-editing stint -- and her important mental health initiatives -- read the report from HuffPost UK.

The duchess chose a very "newsroom chic" look for the occasion, even though her temporary newsroom is actually just one of the many rooms in Kensington Palace. She topped her tweed Dolce & Gabbanna skirt with a high-neck chiffon button-down blouse from Reiss that retails for $230.

As with most things the duchess touches, the blouse is now sold out in nearly every size, but as of 8:15 a.m. EST are still some limited quantities available.

So, you know, hop to it!
