The NFL is officially back! With Week 2 of the regular season in play, we’re gearing up for some major matchups while taking in all of the incredible fashion moments Week 1 had to offer. While we love nothing more than a Sunday spent on the couch watching football, we also love scrolling our Instagram feed for the best game-day looks—and our SI Swimsuit models certainly delivered this past week.

Below, take a look at some of the highlights, all of which serve up some incredible game-day outfit inspo for your fall fashion mood board.

Brittany Mahomes

For the Kansas City Chiefs game against the Denver Broncos on Monday, Sept. 14, Mahomes opted for a dark denim ensemble, made up of a cropped blazer-like top and cuffed denim pant set by ALAÏA. The two-time SI Swimsuit model accessorized her monochromatic look with a white Alexander McQueen purse and pointed-toe boots by Coperni. In her Instagram post of the look, the mom of three expressed her gratitude for seeing husband Patrick Mahomes back on the field following the torn ACL and LCL injury he sustained last December.

Claire Kittle

For the occasion, she wore a 49ers graphic three-quarter-sleeve tee and a pair of slouchy brown pants. As her husband, George Kittle, was also coming back to the field after injury last season, she likewise penned a heartfelt message regarding his return on Instagram.
