Tips

If the foam tunic arrives wrinkled, hang it up in a steamy bathroom or use a low-heat garment steamer to smooth out the creases.
Wear comfortable shoes, as the tunic leaves your legs completely free for walking and mingling.
For outdoor events, the roomy tunic easily fits over a warm jacket or hoodie.
Keep your arms free to carry a trick-or-treat bucket or a drink by ensuring the armholes are wide enough.
