You can expect to see everyone from Sarah Jessica Parker to Reese Witherspoon—even the cast of Stranger Things—wearing it tonight: The Time’s Up pin is the official marker of the #TimesUp movement, the legal defense fund started by A-list celebs who are banding together to help banish sexual assault, harassment and inequality in the workplace.
But where can you buy the pin? It’s available for preorder in the Time’s Up store for a grand total of $12. (FYI, all proceeds go to the movement.) There’s also quite a bit of other merch available to support the cause—everything from T-shirts to totes, notebooks and more.
Time’s Up, which launched a little over a week ago, has already raised more than $16 million. If you want to participate, snapping up a chic—and celeb-worthy—pin seems like the easiest place to start.
