Halloween is approaching swiftly this year. I, for one, am super excited. This is my last year of college before I graduate, so you better believe I’m going to all of the Halloween parties on campus. They are always a blast and are a great way to meet new people and make friends.
I usually go with a few of my besties just because it’s more fun that way. If you are also planning on going to a party as a group of 3, you have come to the right place. I have gathered over 30 of the best trio Halloween costume ideas that are for sure going to win you the “best costume” award.
From arrested princesses to frat boys and Starbucks drinks costumes, there is something in here for everyone! If you are planning on attending parties on campus, you’re going to need more than just one costume. Halloween on campus lasts for at least two weeks, and you don’t want to wear the same costume to all of the parties.
So, pick out 3 or 4 costume ideas and recreate them. You can also take an idea from here and DIY it to make it more unique and creative.
