You should wear red today primarily because it is "Wear Red Day" in the United States, observed on October 14, 2025, as a grassroots initiative to commemorate the birthday of Charlie Kirk, a conservative activist. Supporters across the nation are wearing red, particularly red "FREEDOM" shirts, as part of a movement honoring his legacy and raising awareness through social media and a Senate resolution.

Additionally, wearing red is often associated with other important causes such as raising awareness for heart disease (especially women’s heart health during the February Wear Red Day) and honoring missing and murdered Indigenous women on Red Dress Day in May, though these are not the reasons for wearing red today specifically.

So, wearing red today shows your participation in the Charlie Kirk remembrance and support movement nationally recognized on this date.
