Margot Robbie's showing off her maternity fashion sense on the big stage -- making her first public appearance since revealing her pregnancy at Wimbledon.
The "Barbie" star dressed up her baby bump in a white and black polka dot maternity dress Friday at the All England Club in London.
Margot and husband Tom Ackerley were all smiles as they watched Carlos Alcaraz and Daniil Medvedev battle on the Centre Court grass ... and the expectant parents even smooched in the stands during the semifinal match.
