Wear your worst shirt. Share a selfie.

Make a Donation. Spread awareness for Duchenne.

Bad Shirt Friday is a global awareness campaign to help shine a light on Duchenne muscular dystrophy. On Friday, September 4th, we invite you to wear your loudest, most outrageous shirts and share a selfie on social media using the hashtag #BadShirtFriday.

As we approach World Duchenne Awareness Day on September 7th, each ugly shirt worn is a bold, visible way to spark curiosity and start conversations about Duchenne—its challenges, the urgent need for therapies, and the strength of the families and individuals it affects. And have some fun!

How to Participate

  1. Wear your worst shirt on Friday, September 4th.
  2. Take a selfie (solo, with friends and family, at work, at school—wherever!).
  3. Post your photo to Instagram, Facebook, LinkedIn, or Twitter/X with a caption (see sample captions below) and the hashtag #BadShirtFriday.
  4. Make a donation. 
  5. Tag 3 friends and challenge them to share their bad shirts.
  6. Tag PPMD and any other Duchenne organizations.
