An easy to make, cheap, but good halloween costume?

My friend is having a Halloween Costume Party, so I kinda need a costume.
It's nothing special tho-Just some friends hanging out.
But the thing is, I want a cute costume without having to pay a lot.
I'm not really good with sewing or anything so...

that's not an option.
Also, I'm going with my boyfriend, and it would be cool if our costumes would match eachother. :D
Someone suggested that I should go as an angel and my boyfriend as a devil.
I totally love that idea! But I have no idea how to do it! :D Lmao, sooo..any help, suggestions?

cut out card board wings lol
just wear white all over and maybe try and make a halo

cut out card board wings and tie and punch wholes in both of them near the center to tie them together. thentie then in someway attach it to your shirt. where a simple white dress. for a halo get a wire and make it in the shape of a halo and somehow I dont know how attach to your head
