i need a cheap white petticoat for my alice in wonderland costume! help?

okay, so.
i saw this really cute Alice In Wonderland Costume on torrid.com, and it says that it doesn't come with the white petticoat.
i found some socks and shoes, and all i need is a plus size petticoat for cheap!

Go to your local thrift store. They should have plenty of them out at this time of year!

You can also call the local bridal shops and see if they would rent one to you.

Good Luck!!
