Duchess Kate again wins style cheers for charity

Duchess Kate does it again: She showcases a frock you can hardly believe is a maternity outfit.

For an event celebrating foster-care workers and fostered children in London, Kate chose a dark-chocolate shirt dress with a faint animal-print silk jacquard by Hobbs London.

At just under $100, expect that to sell out soon.

It was Kate's second public engagement of 2015, her second in two days, and the second involving the 6-months-pregnant duchess charming and being charmed by cute little kids.

On Thursday, she opened an art-therapy room in a primary school in London.

On Monday, she's due to appear at three separate events (two schools and a leisure center), all involving children.

The Fostering Network, which hosted the event today, was naturally thrilled at the attention she brought to their mission.

Kate had tea, collected armfuls of flowers and met dozens of children. All of it was chronicled in The Fostering Network's stream of tweets, not to mention those from watching royals reporters.

According to the Daily Mail's Rebecca English, Kate fell for one cute baby called Naya, calling her "sweetie pie" and cooing that she was "chubbier" than her own 18-month-old son, Prince George.

Kate is due to give birth to her second child in April, and many in Britain are hoping the new fourth-in-line to the throne will be a princess.
