If you are aGemini, Halloween may be one of your favorite holidays.
you’re able to definitely go with the whole twin theme for a zodiac-inspired costume.
It even works for couples or friends costumes if you want to dress all matchy-matchy with another person.

You could even do something truly adorable by twinning with your pooch.
(Bonus points if you’re free to manage a similar hairstyle.)
The basic concept might involve dressing both sides of your body in opposite colors.

Both of these concepts could make Halloween costumes.
A bonus is that neither one is particularly difficult to throw together, even at the last minute.
It ends with a pair of deely bobber “antennae.”

For a butterfly, just add colorful wings instead of stripes to your base outfit.
Poster board attached backpack-style with ribbon arm straps also works (viaAlpha Mom).
You will need some pretty large boxes for an adult-sized costume, though.

Another super easy, air travel-related costume is something dreamt up by bloggerDesert Chica an air traffic controller.
Desert Chica made her marshaling wands (oh, so that’s what those things are called!)
This concept lends itself to quite a few costume ideas.

Don’t forget the mustache!
You could also attach cardboard wings to your shoes to complete the look.
For inspiration, think of the FTD logo (viaExotic Flowers).
