It's been a tough third pregnancy for Catherine, the Duchess of Cambridge.
But despite suffering from the rare condition hyperemesis gravidarum (a severe form of morning sickness) and being forced to announce her pregnancy early as a result, the mother-of-three never wavered in the style stakes, inspiring sophisticated maternity looks on royal tours and public events right up until her baby's birth.
From double-breasted coats to empire-lined gowns, nothing was off the table for the expecting Duchess.
Halfway through her pregnancy, she visited chilly Sweden, calling for a series of cosy outfits accented with fur hats and puffer jackets. The Duchess later turned on the glam with a gorgeous full-length gown while dining with the royal family of Sweden.
Here we've rounded up 10 of the Duchess' best pregnancy looks:

February 18 - British Academy Film Awards 2018
Kate sparked controversy when she wore this emerald green Jenny Packham dress to the Baftas. Attendees were encouraged to wear black in support of the Time's Up anti-sexual harassment movement, but royals shy away from donning black as it signifies mourning.
