8 Fun Birthday Party Themes
1. Little Italy Pizza Birthday Party

- Invitations: Big Pizza Pie Invitation | Hand-Drawn Pizza Party Invitation

- Party Food: Planning the food for a pizza party is super simple. Whether you order pizzas or have everyone make their own, it’s a super simple main dish. You could serve a side caesar salad with the pizza and some delicious cookies or fudge brownies as a birthday treat.
2. Nancy Meyers Coastal Birthday Party

- Invitations: Hand-Drawn Trendy Blue Birthday Party Invite
- Decorations: We absolutely love this theme. It’s perfect for anyone who loves the classic Nancy Meyers aesthetic — it’s coastal, girly and so unique. Staying in line with the theme, choose decorative items that are classic, blue and white hues and have a nod to the cozy feel Nancy Meyers is known for.
- Solid White Table Cloth
- Melamine Blue & White Stripe Plates
- Black & White Birthday Banner
- White Paper Lanterns
- Hygrandgeas
- Use woven baskets for a “gift wrapping”
- Party Food: A coastal theme means coastal food, so for a main party dish, lobster rolls would be such a fun and unique food item to serve. For dessert, we were inspired by Nancy Meyer’s film, The Parent Trap, and thought peanut butter oreo cheesecake cookies would be a delicious birthday treat.
3. The Office Birthday Party

- Invitations: The Office Inspired Birthday Invitation
- Decorations: If you love the show The Office then, this would be the perfect birthday party theme to recreate for your birthday this year. There are so many fun directions you can go with decorating your space, so here are a few of our favorite decor ideas.
- Party Food: There are a lot of food references in The Office, but a couple of our favorite are Kevin’s chili and the infamous pretzel day. Rightfully so, we thought those would pair amazing together and be a crowd favorite. As for a cake, you can be as basic or creative with it as you want and make it perfect for the birthday girl.
4. Summer Picnic Birthday Party

- Invitations: Picnic Delights Invitation
- Decorations: A birthday picnic is such a fun and casual way to celebrate your birthday with your friends during the warmer months of the year. Classic americana decorations just seemed right for this birthday party theme.

We’re thinking hearty sub sandwiches, fruit, vegetables, crackers and cheese and for drinks some cold Olipops. For a birthday treat, a gorgeous berry cake would complete the menu.
