Yeah baby. The concept of an Austin Powers-themed party may not be new, but this corporate event gave it a unique and imaginative perspective.

Not to mention, the clever menu names and serverware guests uncovered across the occasion.
Event inspiration — and lunch — is served.

Meet us at this Midnight-themed Bat Mitzvah party. The Miami celebration took Taylor Swift’s second latest album and made it an entire event design. The album cover’s signature deep blue hues encapsulated every inch of the outdoor venue, from shades of blue sparkling off of mirrored furniture to neon ropes lighting up palm tree trunks. And we have to sing the praises of the midnight blue Shake Shack burger stand.
Bring the desert to you. This 60th birthday created a private “music festival” for friends and family thanks to an epic beach setup. The party décor was anything but dry, with luxe lounges built into the sand, an intricate laser cut DJ booth backdrop, a “main stage” inspired bar, and elaborate sea creature-inspired sand castles framing the scene.
Welcome to the future. It’s no secret AI has taken over. From professional to personal use cases, it seems everyone is getting on board with systems that will do the work for you. Rather than fight the change, this Bar Mitzvah celebrated it. The party infused artificial technology-inspired prints and details into its design. Then took it one step further by incorporating actual AI into the party space via large-scale screens and projections that ran throughout the night.
Welcome to 1942. Guests stepped out of Los Angeles and into Rick’s Café Américain at this Casablanca-themed birthday. The event design evoked nostalgic glamour and romance with velvet red draping, antique props, a 250 pound bronze orb, and tropical projection lighting that covered the venue from floor to ceiling, and As for the guest of honor? Here’s looking at you, kid.
The Irish countryside never looked better (even from Orlando). This birthday party was all about celebrating the guest of honor’s Irish heritage — and we love this theme idea for absolutely any culture. A few of our favorite moments include the floral sheep (yes, really) that popped up across the venue, and micro oak kegs that served as the perfect guest place cards. Not to mention, the monogrammed “pub” that celebrated the birthday boy — and offered guests endless spirits out of Ireland all night long. Now we understand why they call it the luck of the Irish.
Paint the town — whatever color you want. A fun-loving expression turned into a food-focused party theme at the San Francisco Museum of Modern Art. Paint chips and color swatches lined catering stations, while apps were passed atop splattered serveware and next to colored paint cans. Waiters and waitresses wore paint splashed aprons and berets as guests dressed to impress in outfits inspired by their favorite art pieces. The best part? Each menu item was a work of art in itself, from artful hors’devours to painted macarons.
This one’s for the millennials. Take guests back to your favorite decade like this 2000s-themed birthday party. Guests arrived in their best bedazzled jeans and butterfly clips to find retro lockers, electric purple fringe, and neon pink furniture. If we didn’t know any better, we’d think we walked into Lizzie McGuire’s closet.
Take your garden party to the next level with an in-season veggie or fruit theme. That’s right, this summer dinner party was inspired solely by the host’s love of tomatoes. From vines of grape tomatoes dressing the bar to bowls of roma and cherry tomatoes on tabletops, guests were treated to the freshest of dinner designs — and menus. Dishes were infused with juicy tomatoes, of course, while the menu itself was scribed in a sundrenched tomato hue. All to say, we’re planting the seed for more produce-themed dinner parties this year.
A good party is often defined by its entertainment — and there’s nothing quite as entertaining as a Cirque du Soleil performance. Turn that into a theme and you’ve got an equally unique and epic event. This Bat Mitzvah evoked all the senses with immersive designs, photo ops, performances, and more. In true Cirque style, guests stepped right up to an imaginative circus, far from the traditional carnivals of the past. We would buy an entry ticket now if we could.
XOXO. Any Gossip Girl fan remembers the iconic masquerade ball episode — and this 21st birthday party made an entire party theme out of it. Decadent draping, a wall of chic eye masks, dripping hydrangea arrangements, and plenty of flickering candles set the scene for a moody, Manhattan-inspired night. Trust us, a unique party theme like this will appease even the pickiest of Upper East Siders.
Salvador Dali’s imaginative and bizarre artwork came to life at this 60th birthday dinner. A theme so funky, fresh, and clever we can’t believe we didn’t think of it ourselves. The dreamscape setting came to life with floral-bound frames quite literally framing tables, making the dinner itself a work of art. Funky furniture, place settings, and neon backdrops completed the eccentric celebration.
Who doesn’t love snack time? When this Bar Mitzvah planner asked the guest of honor what he likes as they brainstormed a party theme, he replied snacks — and the rest was history. The bodega-inspired celebration featured shelves of pantry items, a snack bar (of course), and passed apps including Ramen noodle cups and bags of french fries. Custom monogrammed boxes of cereal, cookies, crackers, and more propped photo ops and backed bars. Was this the best Bar Mitzvah menu ever? We imagine young guests thought so.
Are you ready for it? For Abby and Phil’s wedding welcome party, they greeted guests to their very own “eras tour” — symbolizing notable milestones and stages from their own love story. The experiential party theme took guests through time with cocktails and beverages, including a “freshman year” corner with red solo cup cocktails. To take the theme a step further, guests found themselves with backstage passes and personalized tour merchandise. We imagine this party theme will be remembered All Too Well.
From Dior to diapers, this expecting mom did not hold back when it came to an all-encompassing baby shower theme. The designer theme design was all in the details, from a “Parfumerie” to a “Fleurs” bar, and a pink-draped tent that set the scene. Not to mention, every element was covered in the party’s signature blush pattern — lamp shades, menus, charger plates — you name it, this team thought of it. Our favorite part might have to be the passed pink mocktails, or maybe the designer pink chocolate covered strawberries.
“The team. The team. The team.” That may be Michigan football’s motto, but it’s also the secret to the perfect themed party.

When it comes to a creative party theme, leveraging your favorite team is always a win.
Palm Beach inspiration was all the rage last year thanks to Kristin Wig’s iconic performance in Palm Royale. And with season 2 already in the making it’s no surprise that the glamorous town is still a hot topic — and party theme. This milestone birthday party not only took inspiration from the hit series, but also The Colony Palm Beach, a boutique hotel known for coating every inch of its spaces and rooms in the destination’s iconic pink and green palette. The theme pairs retro moments inspired by the show with glamorous hotel details, including a room key wall in place of a classic seating chart.
Is pickleball becoming America’s pastime? The the paddle sport has skyrocketed in popularity — and will certainly be an epic party theme in 2025.

Throw in an actual pickleball court for guests to play and you’ve served up the perfect experiential party theme.
The first Monday in May is iconic for a reason. The annual MET Gala is host to some of the best red carpet fashion moments of the entire year —which made it the perfect inspiration for this Vogue-worthy wedding.

From a sprinkle donut bathroom mirror to a cotton candy photo booth, our mouths are watering at every sugar-inspired corner.
“Just fold it in!” Schitt’s Creek may be over, but the love for its 80 episodes will never fade. This wedding after party took inspiration from the couple’s favorite series — and of course, their favorite character Moira Rose. “Moira’s Wig Bar” was the perfect way to make a unique party theme moment an experience for guests — even if they don’t appreciate the brilliantly selfish character that is Moira, they can still enjoy her need to have a wig for every occasion.
A sweet bridal shower deserves an adorable theme, and this “She’s off the market” celebration was as clever as it is cute. As a prequel to the bride’s upcoming Lake Como wedding, the shower brought inspiration from Italian markets to the table. Fresh flowers emerged from ceramic colanders, while fresh focaccia filled plates. Caterpillar tablescapes, striped signage, and citrus details were just the cherry on top.
Where has the time gone? It feels like just yesterday Lily Collins as Emily was starting her journey to Paris on the Netflix show Emily in Paris, and now the series is renewed for a 5th season. Bat Mitzvah guest of honor Emelie used the series’ lasting success to her advantage by making it an entire party theme — and casting herself as the main character, of course. Street performers, French cafes, macaron carts, and a floral Eiffel Tower were just a few of the elements that transported guests from New York to the capital of France.
Where there’s a classic saying, there’s a party theme.
