The Kansas Chiefs tight wore a charcoal gray blazer over a white Marni tee to the event — a shirt emblazoned with a blue scribble design of a three-tiered cake with rose piping. Fans immediately began speculating that the print was of a wedding cake, wondering if Travis' top was a hint that he and Swift had tied the knot. (The couple have notably never commented on rumors of an engagement or wedding.) While the pair have also not commented on the T-shirt theory, the Marni shirt, according to the luxury fashion siteSSENSE, is in celebration of the brand's 30th anniversary.
