Now, as to why Brad's sporting this fun, contemporary style ... we've got a few ideas -- starting with his six kids.
The movie star's got six kids he shares with ex-wife Angelina Jolie ... the oldest, Maddox, is 22, and the youngest, twins Knox and Vivienne, are 15 -- so, it's entirely possible he's trying to match their own fire styles.
On top of that ... our boy Brad's got more rizz than almost anyone in the celeb dating game right now -- he's been linked to the likes of Emily Ratajkowski and Nicole Poturalski since his 2016 divorce -- and he's got a new lady in his life.
She's not pictured in these photos ... but we know he's been dating Ines de Ramon -- a jewelry designer with exquisite taste. So maybe Brad's upping his style game with some newer outfits to keep impressing her.
