Bring the classic Hasbro board game to life with this creative look.
The Operation board game costume transforms you into Cavity Sam, the iconic patient with a glowing red nose and removable ailments. It is a highly popular choice for teachers, couples, and retro game fans because it is instantly recognizable and easy to customize. The look consists of a nude or gray base outfit adorned with felt game pieces, a red nose, and a pair of oversized tongs.

How to put it together
- 1
Lay the sweat suit flat on a clean table or floor.
- 2
Cut out the classic Operation game shapes from red felt, including the funny bone, wishbone, broken heart, and spare ribs.
- 3
Cut slightly larger matching shapes out of white felt to serve as the border outlines, then glue the red shapes onto the white backing.
- 4
Arrange the completed felt pieces onto the sweat suit to match their anatomical locations on Cavity Sam.
- 5
Secure the pieces to the fabric using fabric adhesive, safety pins, or hook-and-loop tape.
- 6
Put on the sweat suit, strap on the light-up red nose, and carry the metal tongs as your main prop.
Makeup & hair
Keep hair simple or pulled back. Use a touch of red face paint on the tip of your nose if you prefer not to wear a physical plastic nose.
