You will need
1. Dark slacks
2. White button up shirt
3. Constructions paper, pink, red, black.
4. Some old glasses frames, preferably plastic
5. A piece of string
6. Some paper glue.
7. A couple pens.
Step 1: Make the Mask
once you have the size right and the mask is glued into a ring, glue your eye glasses to the front. Elmers glue worked for me, but I had some plastic glasses frames.
Cut out a tear drop shape for the nose and affix to the glasses.
Now cut out the eye holes.
Step 2: The Tie
To tie the tie on, I glued a loop of cardboard to the top of the tie, and ran a piece of string through the loop.
Step 3: Getting Dressed
Tuck the shirt into the pants. The shirt should puff out a bit. If you are lucky enough to need to, wear a sweater under the shirt to get the puff just right.
For a final touch, put two pens in the shirt pocket.
Just one problem, how to eat the Halloween candy when Dilbert has no mouth.
