In Mean Girls, on which day does Cady Heron say the Plastics wear pink?

In Mean Girls, Cady Heron says the Plastics wear pink on Wednesdays.

Cady narrates the rule while describing the popular clique led by Regina George at North Shore High School. The outfit requirement is one of the group’s many informal social rules, and it becomes a visual shorthand for belonging to the Plastics.

The quote is often shortened to “On Wednesdays, we wear pink,” which is the familiar form used in popular culture. The line concerns the group’s clothing tradition rather than a school-wide uniform policy.

Mean Girls was released in 2004 and directed by Mark Waters. Tina Fey wrote the screenplay, loosely inspired by Rosalind Wiseman’s 2002 self-help book Queen Bees and Wannabes. Lindsay Lohan played Cady, and Rachel McAdams played Regina George.
