Tips

  • Faux fur can get very warm, so wear a lightweight, breathable cotton t-shirt underneath your vest.
  • Use bobby pins to secure the heavy horn headband to your wig so it doesn't slip off while walking.
  • Carry a toy microphone or a bubble blower to match the theatrical, dramatic energy of the characters.
  • Brush out the faux fur before heading out to keep it looking fluffy and voluminous in photos.
