Looking for last-minute Halloween costume ideas but not into the DIY costume thing? Save time and money this Halloween with incredibly easy Halloween costumes: onesies. Also called "union suits," these are just like those pajamas we wore in the '80s or the long-sleeve onesies we see on babies year round. You put them on, zip them up and head out ready to party with your friends.

Union suits have been around since the mid-1800s and were designed to be an easier alternative for women who wore complicated Victorian gowns back then. Men rapidly adopted this trend, and now union suits are a common thing to wear during the winter.

And for the ladies who are worried about what this means for your visits to the bathroom, just remember to unzip your onesie and fold the arms inward before rolling down and holding it around knee high to avoid dragging it on the floor. And I don't recommend using the zipper in the back because it tends to be a lot more complicated. 

Head to the comment section and let us know if you already own a onesie or if you liked any of the ones we recommended. Have a great Halloween!
