Poison Ivy Halloween Costume?

I want to go as Poison Ivy from Batman for Halloween. I’m really not sure what to wear for the actual costume or how to do my hair. I know how I’m doing my makeup (Youuuuutube). It needs to be somewhat appropriate because I have to wear it to school, too. I was thinking just a green leotard form We Love Colors, a short green, flowy wrap/ballet type of skirt, and green fishnets and gloves. Of course I would have vines and leaves wrapping around a legand down one a shoulder and arm. But I’m really not too sure. I have long (dyed) red hair, so I don’t need a wig.
