Halloween // Halloween Costumes for Pregnant Couple / Woman

Hello!! Newly pregnant, will be about 5 months pregnant on Halloween. Looking for either a couples costume or solo costume. Ideally something goth, punk, trashy. But can also be not that either. Love references to TV or film, as well as cartoons, but struggle to find much for pregnant women. Open to options and ideas. I am white, hair color changes regularly, rather skinny, but will be pregnant. Not sure what else would help so feel free to ask. Thank you!!
