Plan B Costume
The ultimate emergency backup plan for a hilarious Halloween night.
The Plan B costume is a popular, tongue-in-cheek choice for college parties and Halloween events, depicting the well-known emergency contraceptive pill box. Most commonly worn as a sandwich-board style tunic or a DIY cardboard box, it is a lighthearted, funny costume that is guaranteed to spark conversations. It is often paired with a partner dressed as a 'One Night Stand' for a classic couples' costume.

How to put it together
- 1
Cut two large, matching rectangular pieces of white foam board or cardboard, sized to cover your torso from chest to mid-thigh.
- 2
Sketch or print the 'Plan B One-Step' logo, including the signature blue and orange swooshes and text.
- 3
Carefully paint or glue the printed graphics onto the front panel, ensuring the branding is clear and recognizable.
- 4
Attach two thick white straps to the top inside corners of both panels using heavy-duty tape or hot glue, creating a sandwich-board style tunic.
- 5
Put on your neutral white base clothing (t-shirt and pants or leggings).
- 6
Slip the sandwich board over your shoulders so the printed panel sits squarely on your chest.
- 7
Carry the giant white foam pill prop to complete the look.
Makeup & hair
Keep makeup and hair simple and natural, as the focus of this costume is entirely on the humorous sandwich-board prop.
Plan B for couples, groups, kids & more
- couples
- Pair up with someone dressed as a 'One Night Stand' (a wearable nightstand table with a lamp on top).
- group
- Have friends dress as other pharmacy items, like a giant box of band-aids, a bottle of aspirin, or a doctor.
- Plus size
- The sandwich-board design is naturally adjustable; simply use wider boards and longer shoulder straps for a comfortable fit.
Tips
- Make sure the armholes and neck opening are wide enough so you can easily reach for drinks and snacks at a party.
- If you plan on sitting down, keep the boards short enough (ending just above the knee) so they don't hit the chair.
- Use lightweight foam board rather than heavy corrugated cardboard to keep the costume comfortable for hours of wear.
- Seal any painted graphics with a clear acrylic spray to prevent smudging if it rains.
