For a Mardi Gras party, wear a costume that incorporates the three symbolic colors of the event: purple, green and gold. Wear a courtly-themed costume, such as a jester hat or a queen's cape. Wear multiple beaded necklaces or attach feathers to a masquerade mask.
A Mardi Gras party outfit should be as wild as the event itself. Throw in as many masks, feathers and necklaces as possible. Wear face paint or an intricate mask, or temporarily dye the hair wild colors. Create a custom mask or wear a wild wig in Mardi Gras colors.
For groups attending a party, coordinate outfits together with similar colors or characters. Create a courtly theme with a jester, king, queen and pauper. Wear separate monochromatic outfits in one of the three symbolic colors. Dress head-to-toe in that color, from face paint to hair to shoes. For an interactive idea, decorate masks together and trade them throughout the night.
The colors of Mardi Gras symbolize different meanings, so dress with these ideas in mind. Purple represents justice, green represents faith, and gold represents power or wealth. For a literal costume, dress completely in gold and carry a bucket of chocolate gold coins to hand out to party guests.
