Learn how to make an easy DIY pumpkin costume perfect for adults! Add HTV to an orange sweatshirt and top it off with a handmade pumpkin hat!

What’s more classic than a pumpkin or a jack-o-lantern at Halloween? The best thing about this costume is that it is a great last minute costume.

It’s so easy to make, and it’s really comfortable to wear. It works for both men or women. I wore it to a Halloween party this week, and felt good the whole time.

I chose to do a classic happy face for the pumpkin, but you can do a silly or a scary face instead. It’s great when you make it nice and big and noticable.

I did my face with iron-on vinyl and a Cricut Maker, but if you don’t have a cutting machine you can sew a felt or fleece face onto the front instead.

What fabric works best for a pumpkin costume?

The best fabric to use for a pumpkin costume is felt. I love using felt for costumes because it is easy to sew, and it doesn’t fray. The fabric doesn’t need to be finished!
