International fashion weeks were imminent but there was now a whole other wardrobe to consider.
Kate, who is expected to give birth any day now kept her wardrobe relatively muted at the start of her pregnancy, however, it wasn't long before bright hues returned to her wardrobe.
Burgundy and black tones were replaced by fuchsia, crimson and pops of pattern as the Duchess's baby bump became more prominent.
Kate has navigated the very complex conundrum that is 'maternity wear' like an expert thanks to her innate love of a full-skirted coat, loose-fitting button-down pieces and on occasion a very glamorous evening gown.
Not forgetting her love of outfit recycling - she has reworn numerous look from previous pregnancies with Prince George and Princess Charlotte, in particular a number of cotton dresses and shift-style coats by British brand Goat.
Ending her third pregnancy on a stylish note the mum-of-two decided to dress down for her last official engagement on Thursday wearing a pair of black skinny jeans, a cream coat by Goat and a floral Hobbs top.
Furthermore, Kate impressively stuck to heels throughout her pregnancy remaining loyal to her round-toe courts - rotating pairs in navy, nude, pale grey and black.
