Week 4 of the NFL season has arrived, and the calendar has officially flipped to October. But sweater weather hasn't quite followed everywhere.

Unseasonable heat out West could keep layers light for another week, while cooler temperatures settling in across the East are opening the door for more fall-ready fits. That means players have plenty of options as they make their Week 4 entrances. With three weeks of looks already in the books, personal styles are also starting to take shape around the league. Some players have leaned into statement pieces, while others have kept things clean and understated.

From warm-weather looks to seasonal layers, Week 4 brings another round of game-day style as the calendar officially turns to fall.

Thursday night's fashion

Players and coaches aren't the only ones showing off their style pregame. Mascots get in on the tunnel fits, too. This week, Brownie the Elf was ready to rock for Cleveland's Rock & Roll Hall of Fame Game, channeling Prince in a purple jacket with a matching guitar.
