The pregnant royal visited Macarthur Girls High School in Sydney on Thursday, day four of her Australia tour, in a gorgeous navy blue, bi-color A-line midi dress by London-based brand Roksanda.
The elegant frock's flattering silhouette draped over the duchess' growing tummy, complemented by the same suede nude Stuart Weitzman pumps the brunette has donned multiple times during her tour with Prince Harry.
Changing it up from her usual waves and messy bun, she debuted a pretty hairstyle -- a half-up-half-down 'do with a slight voluminous crown, effortless, romantic waves and loose strands that framed her glowing face.
The Duchess of Sussex, 37, watched a dance performance outdoors alongside her husband, 34.
Earlier in the day, Markle visited Bondi Beach in a stunning striped maxi by Australian designer Martin Grant. She was spotted cradling her bump as she beamed on the iconic beach.
