I always want to do something awesome for Halloween and it never really happens. The internet tells me I can make a mummy costume, or become a lego version of myself with only my innate make-up ability and 10 minutes. That way ends in disaster.
I also want to go for something scary, rather than all the silly popular culture inspired ones that proliferate the interwebs, but that limits the options further. I went for something in the middle, not a witch or vampire but also not a humanoid emoji or confectionery item. I chose cave girl.
I bought some pretty cheap cheetah fabric and sewed a really simple dress, essentially a big tube with elastic sewed into the top to keep it on. I added a very simple strap on the right side to the top, and cut the bottom all jaggedly to make it look like it was ripped straight from a poor little cheetah. I also cut a ragged strip to tie around my waist as a little belt, mainly to make the shape of the dress more flattering. And I made a little bag out of the same fabric to match. I then cut some thin sheets of white foam into bone shapes for a necklace and hair accessory.
