Diana doesn't wear a bra the entire movie and you can see the outline of her nipples throughout. (This is inaccurate, also inappropriate and irrelevant: an obsession with nipples showing through clothing. The statement that Diana doesn't wear a bra throughout the movie is inaccurate/false, as in various outfits in various scenes her bras outlines are apparent under her shirts/tops.)
