Tips

If using a foam tunic, steam or hang it in a steamy bathroom a few days before wearing to remove fold creases.
Wear lightweight layers underneath, as foam tunics can trap body heat when indoors.
Ensure your armholes are cut wide enough if you are making a DIY cardboard version so you can easily reach for drinks and snacks.
