Going through photos of Naomi Osaka‘s 2019 outfits, I almost can’t believe she started this year in Adidas! I’m so used to her wearing Nike now that the big WTA fashion switch seems to have happened years ago.

Let’s review all Naomi Osaka’s 2019 looks as part of my traditional Fashion Retrospections.
