Have an IDEA!!!
I would like to offer you an idea of making precise and inexpensive costume for the masquerade.
How often you wanted to go to the masquerade (despite that fact that it not so often it is still happens) and suddenly found that there was no any suitable cloth in your wardrobe and any idea of creating the costume in your mind?
If you are that kind of person who wants to have fun and can't stand being just an ordinary person you can even get crazy trying to create an extraordinary costume. If you wish to strike people as super eccentric and crazy person so visit the masquerade in Adam and Eve costume.
You don't need anything at all for this just your body :) and some courage of course. And I promise you will be the most popular person at the party. Good luck ;)
