How to use my bridesmaid dresses as Halloween costumes?

I have one peach colored, lacy bridesmaid dress, with only one sleeve. It’s floor length and still in really good shape. It has a straight skirt.

I also have a red bridesmaid dress that is lacy. It has a floor length skirt, too, but its skirt is very poofed out, and layered. It’s spaghetti strapped.

Any suggestions on how to use these as easy Halloween costumes?
