1. Icon in Ivory: An Old Hollywood Glamour Party

Inspired by: The Davis (The Cream Phone)

Get ready to roll out the red carpet! This birthday bash is pure timeless elegance with a touch of movie magic! Picture this: vintage film reels, glittering champagne towers, and a soundtrack filled with swoon-worthy crooners and silver-screen sirens. Whether you're celebrating your 30th or your 60th, this serves main character energy and lets everyone feel like a star.

Tips to Pull It Off:

• Dress the Part: Invite guests to channel their inner classic icon — think monochrome looks, black-tie glam, and vintage Hollywood flair (bonus points for elbow-length gloves or a sharp tuxedo).
  
  
• Set the Scene: Decorate with old movie posters, golden marquee lights, and luxe fabrics like velvet and satin for an authentic red-carpet vibe.
  
  
• Sip in Style: Serve mini martinis, oyster shooters, and champagne in dramatic glassware that evokes a 1940s supper club.
  
  
• Capture the Magic: Place The Davis near a glammed-up faux film set, complete with directors’ chairs and spotlights, for guests to leave “screen test”-style voice messages you’ll treasure forever.

2. Hot Stuff: A Retro Dance Floor Throwdown

Inspired by: The Donna (The Green Phone)

Slide into your platforms and dust off your best disco moves — it’s time to boogie! This bash is pure '70s soul, packed with glitter, funk, and all-night grooves, with just enough 2025 sparkle to make it feel fresh. Think Studio 54 energy but with better snacks (and way cooler phones). 

Tips to Pull It Off:

• Bring the Bling: Rent a giant disco ball, set up an LED dance floor, and toss in a few strobe lights for good measure.
  
  
• Dress Code: Encourage guests to go all-out with bell-bottoms, metallic fabrics, sequins, and as much glitter as they can handle. The shinier, the better!
  
  
• Snack Attack: Keep the retro spirit alive with a fondue station, colorful cocktails garnished with umbrellas and cherries, and a late-night spread of "midnight munchies" like sliders and fries.
  
  
• Record the Groove: Set up The Donna near the dance floor and let guests leave song dedications, hilarious party stories, and heartfelt birthday messages — all with that unmistakable disco flair.

3. Let’s Dance: Futuristic Glam Rock Celebration

Inspired by: The Bowie (The Orange Phone)

This birthday bash is for the bold, the brilliant, and the beautifully extra. Get ready for a night where space-age sparkle meets rock ‘n’ roll rebellion. Picture holographic textures, electric face paint, and enough glitter to light up the next galaxy — it’s Ziggy Stardust energy reimagined for 2025 — the ultimate vibe for anyone who was never meant to blend in.

Tips to Pull It Off:

• Shine Bright: Set up a glitter bar where guests can deck themselves out in sparkle, then send them over to a neon-lit photo booth to capture the cosmic chaos.
  
  
• Dress Code: Encourage metallics, fringe, platform boots, and anything remotely intergalactic. Channel your inner rock star or celestial explorer — no look is too over-the-top.
  
  
• Soundtrack the Stars: Curate a playlist packed with glam rock legends, synth-pop anthems, and a few futuristic beats to keep the energy sky-high.
  
  
• Space for Memories: Station The Bowie under a canopy of laser lights so guests can leave voice messages that sound (and feel) truly out of this world.

4. Edge of Seventeen: A Dreamy Boho Bash

Inspired by: The Stevie (The Red Phone)
Cue the flowing fabrics and flower crowns — this birthday vibe is pure magic. Perfect for backyard birthdays, beachside sunsets, or anywhere the breeze can catch a fringe, this bash blends a carefree spirit with just a bit of mystic energy. It's dreamy, soulful, and worthy of the birthday star who's always dancing to their own beat.

Tips to Pull It Off:

• Create Cozy Corners: Layer vintage rugs, mix-and-match throw pillows, and scatter candles everywhere to set the scene for laid-back lounging and late-night conversations.
  
  
• Add Some Magic: Set up tarot readings, crystal charging stations, or a DIY flower crown bar to keep the good vibes flowing.
  
  
• Serve Up the Charm: Build beautiful charcuterie boards and offer botanical-inspired cocktails with herbs like lavender, rosemary, or mint.
  
  
• Capture the Moments: Tuck The Stevie into a cozy, macramé-draped nook where guests can leave heartfelt voice notes — the kind you'll want to listen to under the stars for years to come.

5. Cool Kids Club: A Chic All-White Bash

Inspired by: The Billy (The White Phone)
Minimalist meets maximalist in the best way possible with this pristine, party-perfect vibe. It’s your scene if you live for sleek rooftop lounges, Instagram-worthy moments, and setting trends instead of following them. It's crisp, cool, and totally unforgettable — because when everything’s white, you and your crew bring all the color.

Tips to Pull It Off:

• Style the Crowd: Everyone wears white,  but encourage a mix of textures like silk, linen, denim, leather, and even feathers to keep it fresh and dynamic.
  
  
• Design the Space: Think sculptural floral arrangements, clean modern lines, and a few well-placed neon signs for a little extra pop.
  
  
• Elevate the Menu: Serve sophisticated bites like sushi towers, caviar-topped blinis, and white sangria or lychee martinis to keep the vibe effortlessly luxe.
  
  
• Make It Iconic: Set The Billy on a chic pedestal near the party action so guests can leave voice notes — love letters, inside jokes, and all — in serious style.
