Halloween is coming so lets focus on red fabric dyeing. You can create costume elements that can still be worn again on Nov 1st:
Red Fabric Halloween Costume
One of the easiest costumes is Little Red Riding Hood. A simple piece of draped red fabric can stand in for a hooded cape. When you are using fabric dye doubling the amount of dye gets vibrant results with bright colours.
PLL Halloween Costumes
For a halloween costume update wear a red coat for a Pretty Little Liars themed costume ‘A’ would approve of.
The show's 'A team' always wears an all-black wardrobe, so you could easily wear a black hoodie. Remember to always double the amount of black dye to get the darkest results.
