7) RIP to My Teens

A 20th birthday party growing in popularity is the “RIP to my teens” birthday party. To pull this off, you and all of your party guests will need to wear all black (as if they’re attending a funeral, haha), black cake, and black decor. You could have also a slideshow of pictures of you in your teen years running in the background to reinforce your “RIP to my teens” themed party.

But it’s a celebration, so the food and the music will make this super clever party a great time for everyone!

8) Intimate Italian

If you are having your party at home and you’re obsessed with Italian food, make your birthday theme Intimate Italian. Set the mood with Italian music and offer your favorite Italian appetizers to start.

For lunch/dinner, you can have a make-your-own pasta bar, invite a chef to teach you and your guest how to make or serve gourmet pizza yourself, and offer a variety of Italian cocktails.

9) Garden Themed

Another popular 20th Birthday theme is a garden-themed party. You can eat high at a table together with friends, or rent several high tops to be placed throughout your backyard or outdoor location. You can even eat low with your friends around a small table set up on the ground with pillows and rugs.

10) Breakfast at Tiffany’s

If you love breakfast or brunch, then a perfect 20th Birthday theme is Breakfast at Tiffany’s. Have your friends dress in their Sunday best and serve a variety of teas, cakes, and your favorite breakfast dishes.

11) Friends-themed party

If you love the show “Friends”, then throw a Friends-inspired birthday party. All you have to do is make your space look like the inside of the Central Perk Cafe, have a photo booth station that includes the famous orange couch, and have everyone dress as one of their favorite characters from the show.

12) Color Party

How about turning your 20th birthday into a color explosion? Imagine every corner dripping in vibrant hues, from decorations to your cake, and to outfits. You can choose the color(s) of your choice or invite your friends to dress as varied as the rainbow.

13) “Anything beginning with” Theme

A really clever 20th birthday theme, is an “Anything beginning with _” To Pull this off, you would just tell your friends to wear something beginning with…and you fill in the blank. It could be their first name, last name, or you can choose a letter.

14) “Anything but” Theme

If you want a good laugh and want to be surprised by what your friends come up with, have an “Anything but” themed party and choose what they can’t wear or bring to your party.

For example, you can tell your guests to wear “Anything but clothes” and see how they come dressed to your party. You can award the the most clever dresser and make you laugh at your party.

15) Cinema-Themed Party

Another awesome 20th birthday theme is a cinema-themed party. It could be like your own blockbuster premiere where you’re the star! You could do a red carpet, a photo-shoot station, a popcorn station, and cozy seats for the movies.

Before the featured movie, you could show your own movie of your journey so far and have your guests talk about their favorite moments with you up to this point.

16) Legally Blond

If your dream is to become a lawyer one day and you’re obsessed with the movie Legally-blond, then have a legally blond-themed party.

To pull this off, you’re decor would be pink everything and your dress code would be pink (or mostly pink). For fun, your friends could create a TikTok of doing the bend-and-snap and party, and take a bunch of Polaroid photos, before, dancing the night away with great music.

Also, Elle-woods loved doing her nails and getting her hair done, so you could also do something more chill and laid back, and have a DIY spa night with your girls instead.

18) Mean Girls

If you loved the movie Mean Girls, then it would make a great 20th Birthday theme for your party. Imagine Pink decor, witty quotes, and maybe even a Burn Book for laughs. It’s not just a birthday; it’s a chance to channel your inner Regina George with your ride-or-die crew and not make any enemies for it afterward. LOL.

19) Neon-themed Party

You could also do a neon-themed blowout for your 20th birthday – because who doesn’t love a splash of vibrant colors, right? Imagine glow-in-the-dark everything, neon lights, and an atmosphere filled with your favorite music.

It could be your very own neon wonderland and would make an incredible backdrop for photos with your guests.

If you choose to go with this theme, one activity I highly recommend you do is one where you and your friends create your very own neon-splash-painted shirts. You can supply the white tees and the paint, and watch you and your friends go crazy.

20) Pajama Party

If you don’t feel like dressing up in a fancy dress for your 20th birthday, do the opposite and slay some comfy PJs with your guests. You can stay up late and have breakfast at midnight, take insta-worthy pics in cute matching sets with fuzzy slippers, and have karaoke night.

21) Animal Print

If you’re obsessed with animal print, an animal-themed bash would make a great 20th birthday theme. From sassy leopard prints to zebra stripes, it’s all about embracing your wild side in style. Invite your guests to wear their best print, and make everything jungle chic from your decor to your cake.

22) Vintage Party

Another way to spend your night in glamour is to throw a vintage-themed party for your 20th Birthday. Play classic tunes, wear chic attire, and invite all of your guests to do their hair in a classic style for your night.

23) Dress as the First Letter of Your name

Finally, how about this for your 20th? A “Dress Up As the First Letter of Your Name” party – where everyone gets to rock outfits that start with their initial. It’s a playful twist, a bit quirky, and a whole lot of fun!

Think about the creative chaos – A for aviator shades, B for boho chic, or C for cocktail glam. It’s not just a birthday; it’s a stylish celebration where individuality shines and the alphabet becomes your runway.
