Taylor Swift Standing on Business, Blazer and Miniskirt at Chiefs Game

Taylor Swift‘s ready to watch her man take care of business against the Denver Broncos … pulling up to his Sunday afternoon game in K.C. in a biz-casual ensemble.

The singer-songwriter rolled into Arrowhead Stadium in a red and black checkered blazer, pulled over a low-cut black top … with a tiny skirt matching her jacket.

Clearly, she’s in her “No-Nonsense Era” … preparing to watch her boyfriend Travis Kelce‘s team beat up on their division rival.

Of course, there’s still a full game to be played … but, the Chiefs have looked really strong recently — including in last week’s overtime win against the Tampa Bay Buccaneers.
