Antonio Brown ... we mustache you a question -- what's up with the dental drapes, man??
The NFL superstar posted a selfie with his son, Auto, on Wednesday ... showing off a bright, new multi-colored dread look ... complete with a bleach blonde caterpillar above his upper lip.
Of course, A.B.'s no stranger to head-turning looks ... remember, he had the Nino Brown/Lego head 'do a few years ago ... and his fashion style is among the most unique in the league.
For a guy who dressed up as a hippo and sang "My Prerogative" in front of a bunch of people, we shouldn't be surprised.
Keep doin' you, A.B.
