I know what you're wondering: Who did Taylor Swift sit with at the latest Kansas City Chiefs game? And more importantly, what did she wear?

A week after she caused a stir for attending the US Open with Patrick and Brittany Mahomes and her boyfriend, Travis Kelce, Swift arrived at the Kansas City Chiefs game on Sunday, September 15 with a new crew in tow.

Swift rolled up to Arrowhead Stadium for the Chiefs game against the Cincinnati Bengals with her mom, Andrea Swift, her brother, Austin Swift, and two-thirds of the sisters Haim, Danielle and Este Haim. Fans were thrilled to see Andrea repping an "87" jacket, which was, essentially, an official endorsement of her daughter and Travis Kelce's relationship. Not that we didn't know the whole Swift family was already on board with the whole Trayvis thing. Taylor's dad, Scott Swift, has attended several games with his daughter, and as well as several Eras Tour shows alongside Travis.

Swift wore yet another pair of thigh-high leather boots with what looks to be a vintage Kansas City T-shirt, basically worn as a dress. This is the third time in a row that Tay has stepped out wearing boots so tall they're practically pants. At the last Chiefs home game, she paired a denim corset and hot pants with red boots; at the VMAs on Wednesday evening, Swift wore another corseted silhouette -- this one by Dior -- with over-the-knee black boots.
