Take 1 full sheet of celophane and fold it in half. On the folded side, in the middle cut out a "head hole". I made mine with a V-neck at the front so there was a bit more breathing room.
Using sticky tape, tape around the "head hole" so that the cellophane doesn't split while you are wearing it. Ultimately you are making a celophane tabbard.
On a long strip of foil use a permanent marker to colour in the logos for the sweet you are making. I did "Quality Street" logos as I was going to a Q party.
Tape the foil with logos to the inside of your celophane. I stuck mine a little bit higher then the bottom of the celophane so I could tape a little turn over "hem" for extra strength.
After this step the main body of your costume is complete.
Taking another sheet of celophane cut it in half length ways. Using to hair ties create little arm cuffs to look like the "twist" endings of the sweet.
Slip on the arm bands and the "tabbard". You can tape closed the side parts if you would like. I left mine open to keep cool.
