'Once Upon a Time in Hollywood' premiere: All the glam red carpet arrivals

"Once Upon a Time in Hollywood," indeed!

Co-stars Leonardo DiCaprio, Brad Pitt and Margot Robbie led the flood of celebrity arrivals Monday night at the premiere of Quentin Tarantino's new film, with DiCaprio sporting a buttoned blue suit and Pitt opting to ditch the typical necktie. Robbie's angelic ivory gown marked one of her best style moments to date.

Pierce Brosnan brought an unexpected +1: His 22-year-old son Dylan, whose light-wash jeans and shoulder-length hair made for an appropriately boho-chic look. ("Once Upon a Time" is set in 1969.) Standing several inches above his dad — who's 6'1!" — it's no surprise that Dylan is an up-and-coming model.
