Are you freaking out because you haven't bought a Halloween costume and you don't know what to do? Well, fear not. There are still a number of last minute ideas that you can pull off before you head out to celebrate Halloween Friday night.

Instead of just uploading selfies all night long, why not become a selfie?

In order to dress up like an Instagram picture, you can print and attach Instagram logos to a colored acetate sheet, which is available at your local art supply store, notes the Huffington Post. You can also use off-white tissue paper attached to a poster board and then paste Instagram icons to the poster board. Now, all you have to do is hold it up in front of your head and make the infamous duck face. Your friends will get the picture, literally!

You can also dress up like the Ice bucket challenge. In order to pull off this costume, fill a bucket with packing peanuts. Pretend you're drenched in water by cutting holes in a see-through trash bag. Then act very competitive and attention-seeking.

For another idea, try wrapping yourself in aluminum foil and calling yourself a baked potato.

You can also choose to dress up like Waldo, which is easy to do since all you need is a pair of big glasses, a red and white striped shirt and a red beanie.

This Halloween, you can also dress up as Carmen San Diego. All you need is a yellow scarf, a red hat and a red jacket.

Dressing up as a weather man is also a fun idea. Just put on a windbreaker and tape leaves and pieces of trash to yourself. Make sure your hair isn't combed and hold a fake microphone.

Just in case that's too complicated, you could also personify identity theft by covering yourself with name tags of the names of your friends and/or celebrities.

Millennials can also enjoy dressing up as a hashtag. All you need to do is use paper or cardboard to create a wearable pound sign symbol.

If all else fails, you can always be a grumpy cat with a cat nose and ears, which should be easy to find at a pharmacy like Walgreens or a dollar store.

Last, but not least, you can also buy a tool belt from the dollar store, throw on a checkered shirt and call yourself a construction worker.

Have fun, and Happy Halloween!
