What's cooler than dressing as one of the hottest girl groups of all time? All this throwback to the 90s requires is sweatpants, basketball shorts and crop tops.

Hogwarts Teachers
Let everyone else dress as Harry, Hermione and Ron while your crew actually causes a scene (in the best way ever) as their teachers.
Inside Out Emotions
The newest emotions from Disney and Pixar's Inside Out 2 will make you the cutest trio on the block. Dress in monochrome colors and face paint to emulate Anxiety, Envy and Ennui. This could also work for a large group if you throw in old emotions Joy, Sadness, Anger, Fear and Disgust.

Dr. Seuss Characters
Pair Cat in the Hat with Thing 1 and Thing 2 for a fun storybook costume. The hardest thing about his costume will be deciding who gets to be who.
Negroni Sbagliato (with Prosecco)
The easiest look our list comes from the viral Emma D'Arcy clip. Use our template for the labels, and just decide who will be which liquor!
The Shelby Brothers
If there's one thing for sure, it's that the Shelby boys have each other's backs. Bonus: You probably already own a suit, so the rest is practicing your menacing look. You can also channel the ladies of the show: Polly, Grace and Ada.
Clueless
As if this movie will ever get tired. There are, of course, a number of great outfits from the movie you can probably DIY, but none are more iconic than the plaid looks.
Power Puff Girls
Few cartoon characters are as awesome as the Power Puff girls. They fight crime, they have a good time and they wear the cutest clothes. You can opt for a DIY route that would just include a dress in the right color.
This fire costume will definitely get people talking. Dress up as a Fireball tank, bottle and shot glass for a night full of fun.
Avocado Toast
For a too-cute family Halloween costume is so easy to make, plus it works as a maternity outfit. If you have a fourth in your family, feel free to have them go as an orange juice.

There are so many incredible outfits you can pick from, but this is one of the easiest. Some silver dresses and microphones, and you're all set.
Sutton, Jane and Kat from The Bold Type
You can literally wear any cool outfit you want and pull-off this costume, making it the ultimate last-minute idea. Maybe just print out a fake Scarlet Magazine to really drive the point home.
