Taylor Swift's helping out Erin Andrews while supporting Travis Kelce and the Kansas City Chiefs ... wearing a jacket from the sportscaster's clothing line to the NFL game.
Sources close to Erin tell TMZ … the NFL broadcaster sent Taylor some items from her WEAR by Erin Andrews clothing line in the hopes Taylor would wear something in the future, and Taylor came through.
We're told Taylor's windbreaker jacket retails for $112 ... and as you can see, it's got the KC Chiefs logos and patches all over the place ... so Taylor fits right in at Arrowhead Stadium.
Taylor's at her third Chiefs game in the last four weeks ... and she's once again cheering on Travis from his suite ... and hanging out with his mom, Donna.
The Thursday Night Football game is part of a whirlwind 24 hours for Taylor ... last night she was in Los Angeles for the premiere of her 'Eras Tour' concert movie, which shut down the world-famous outdoor shopping mall, The Grove.
While Erin's not besties with Taylor or Travis, she does have a connection to the couple ... back in August, Erin played matchmaker on her podcast and suggested the two hook up.
Taylor's fans always seem to snag her outfits ... whatever she wears usually sells out within days of her being seen wearing it in public ... so Erin's gotta be thrilled.
