Once junior year hits, it seems like every weekend another one of your best friends is turning 21. It is a year full of celebrating and making others feel special, as well as a year filled to the brim with *legal* drinking.

But what does one do to celebrate a 21 run? There are infinite ways to celebrate, but there are a few essentials you must have to make sure your best friend has the best birthday ever.

1. The Sign

The sign the birthday girl wears on her 21st is essential. She’ll need it to get her squad into all of the stricter bars and to help get some free birthday drinks. It is the sign that encourages her to make some terrible decisions, but just for one night. The sign she wears is in every picture for the whole night, and it will most certainly be a night worth documenting.

2. The Decorations

When the birthday girl comes to her pregame, it’s important that the birthday vibes are in full swing and all the attention is on her. Backdrops for pictures with the birthday girl are one of the most important aspects of decorating, but embarrassing pictures of her posted all around the room might be the best part of all.

3. The Shot Book

This is the best opportunity to embarrass your friend with all of the blackmail snap chats you have saved of her. It’s a scrapbook filled with pictures from the birthday girl’s 21 closest pals and is hopefully a place to add more pictures from the memorable night to come.

4. The Drinks

It is a day of legality that should be celebrated as such. That is all.

5. The Friends

No matter what, spending time with people that love you will make any day special. It is important that on the birthday girl’s special day that she is surrounded by love and support from the people that care about her the most, no matter how she chooses to celebrate. Being with the people who love you most will make any day a special one.

Happy celebrating!
