Taylor Swift's skipping deal hunting for football on Black Friday ... hitting up the Kansas City Chiefs game against the Las Vegas Raiders with Travis Kelce's fam.
The singer-songwriter arrived at Arrowhead Stadium just minutes ago ... with Travis' mom Donna walking alongside her down the tunnel and into the stadium.
Taylor's in her comfy, cozy K.C.-fan era ... red quarter-zip top and black pants on -- bracing the elements out in Missouri. It's currently 35 degrees in KC -- so, certainly not shorts and t-shirt weather.
