If you’re not sure what to bring, ask your host. They may tell you not to bring anything out of politeness. In this case, respect their request; although, you could still give them a card or a thoughtful note. If you can’t bring a gift, a bottle of wine or vase of flowers are good options.  Potluck: a dish to share. Birthday party or baby shower: a gift suitable for the recipient. Dinner party: a bottle of wine or a hostess gift. Casual high school or college parties: no gift, unless specified. Try to get plenty of rest the night before the party. That way, you’ll be able to stay up late if it’s a late night party. Even if it’s a daytime party, you still want to have the energy to be sociable and feel your best.  Some people will drink coffee or another caffeinated beverage before going out for a late night party. Eat a protein-packed meal before going out. Even if there will be food at the party, you don’t want to arrive starving. Listening to some of your favorite music is the perfect way to get excited about a party. It can get you energized and ready to dance, or just put you in a good mood.  You can listen to music while you’re getting dressed, or while you’re driving to the party! Sing along. You’ll feel confident and expressive, which is a great way to feel when you arrive at a party. Think about who will be at the party and how you want to interact with them. This can be especially useful if you’re shy or don’t go out very much. You can make small goals, such as, “I will talk to two new people,” or “I will introduce myself to my new coworker that I have a crush on.”  You can even practice in the mirror if you’re really shy. Practice introducing yourself to someone by saying, “Hi, I’m ___. How do you know the host?” Think of topics you can talk about with other guests. Do you follow current events? Have you been working on an interesting project? Can you share a humorous story about the host? Usually, it’s assumed that people will arrive at a party a little bit after it’s supposed to start. This is called being “fashionably late.” If you’re shy, you may want to arrive well after the party has started so that you can avoid having to make conversation if there are only a couple of people there early on. Don't be late to dinner parties, children’s parties, or parties where a space has been rented for the occasion. Doing so is considered to be rude. Aim to arrive on time.

Summary:
Prepare anything you need to bring. Get energized. Listen to music. Plan for socializing. Decide when you’ll arrive.
