23 Super Simple Last Minute DIY Halloween Costume Ideas

Halloween always sneaks up faster than we think. One minute you’re picking pumpkins – the next minute your friend texts “I’m picking you up at 7 for the costume party tonight!” – and you realize you have nothing ready.

One year, I had less than an hour before a party and zero costume ideas. After panicking and rummaging through my closet, I pulled out a pair of black leggings and a black long-sleeved shirt, stuffed a black knee high with cotton balls, and taped some cut out black paper triangles to a headband. Add a black marker for some whiskers and a black nose and voila! I was a black cat! 

That’s the great thing about DIY Halloween costumes – they don’t need to be fancy, just creative (and maybe a little punny).  If you’re a last-minute person like me – or broke – here are 23 quick and easy DIY Halloween dress up ideas you can throw together with things you probably already own.
