Costume Ideas Starting with the Letter "G"

Alphabet and Letter Parties

In costume party season, the pressure is on to host a fun, unique party. One idea for a fun party theme is encouraging your guests to choose a costume that starts with a specific letter of the alphabet.

Here are some ways to do that:

  1. Allow guests to dress up in a costume related to their initials (or just their first names if you want to narrow their choices).
  2. Ask guests to dress up in costumes related to your initials.
  3. Choose one or two letters to inspire their costumes. These could be randomly or deliberately chosen.

When you first send out invitations, it's possible that your guests will be confused about what you're asking them to do. To avoid confusion, be sure to explain the idea thoroughly since if your guests are confused, they might not dress up. Even worse, they might skip your party altogether.

This article will give you some ideas for costumes that start with the letter "G," some based on famous characters or people.

If you have any other ideas, please put them in the comments box so you can help other people too.

Have a fantastic party!
