Fancy Dress and Themed Party Ideas

Hosting a garden party is one of the easiest ways to bring people together — no hall hire, no expensive bar tabs, just sunshine (hopefully), good company, and a setting you already know and love. Whether you’re planning something chilled or a bit more polished, there’s loads you can do to turn your garden into the ultimate party space.

Why throw a garden party?

It’s casual, it’s affordable, and it works for almost any occasion — from family birthdays to last-minute BBQs with your mates. You don’t need a massive outdoor space either; with the right furniture, lighting, and cover, even a small patio can be transformed into something special.

Popular Garden Party Ideas and Themes

A garden party doesn’t need a huge budget or professional planner — just a solid idea and a space you can make your own. These themes work beautifully with a pop-up gazebo or marquee as the focal point, and they can scale up or down depending on your guest list.

Games & Grub

This one’s all about casual fun. Mix party food with lawn games — giant Jenga, croquet, rounders, or a big game of musical chairs for adults and kids alike. Have food stations (BBQ, nachos, hot dogs) and a drinks corner with serve-yourself punch.

Perfect for: Family reunions, summer socials, birthday parties
Set-up tip: Use your marquee as HQ for food and drinks. Hang a chalkboard menu on the frame, and keep cool boxes underneath.

What makes a great garden party?

It’s all in the atmosphere. Mix casual seating (blankets, deckchairs, benches) with shaded areas so people can drift in and out of conversations. Have drinks accessible — whether in a barrow full of ice or a side table near your marquee — and let the day roll out naturally.

Music sets the tone. Use a portable speaker and prep a playlist that doesn’t overpower the vibe (if you haven’t already, check out our BBQ Playlist).

Gazebo or marquee? Yes, you absolutely need one.

Even if the forecast looks golden, the great British summer loves to throw in a surprise. A pop-up garden marquee or gazebo gives you control over your space — sun protection by day, warm shelter by night, and somewhere to stick the buffet if ants try crashing the party.

If you’re expecting a handful of guests, a 3x3m gazebo will give you shade and serve space. For bigger numbers or something more decorative, consider a high-arched garden marquee dressed with linings, lights, and furniture. (We’ve got options for both.)

Quick-fire planning tips

• Use solar or festoon lighting to keep the space usable after dark

• Prepare a small music setup and seating around it — people always drift to music

• Keep food fuss-free: platters, BBQs, grazing tables

• Add some personal touches — chalkboard signs, homemade drinks menus, or simple bunting

  
  

Popular children’s party themes that work in a garden

These classic party setups work brilliantly with a marquee or gazebo as the base of operations:

Gazebo or marquee? It makes everything easier.

You’ll have a dedicated place to put the food, hand out party bags, run games, or give kids a quiet moment when it all gets a bit too much. It also gives parents somewhere to hover (or hide) without cramming into the kitchen.

Sizes like 3x4.5m or 3x6m are perfect for these kinds of parties — big enough for a couple of tables and still room to move. You can dress them up with balloons, fabric drapes, lights, and signs depending on how Pinterest you want to get.

Children’s party planning tips that actually help

• Keep the food simple: Sandwiches, fruit skewers, crisps, cupcakes, and a few sweets. Serve everything on trays for quick clean-up.

• Plan one activity every 30–45 minutes to stop them bouncing off the walls (or trampoline).

• Have a backup plan: If it starts raining, shift any activities that need dry space under the gazebo.

• Ask parents to stay and help — most are happy to, especially if they’ve got somewhere comfortable to sit.

Dinosaur Adventure

A classic. Hide toy dinosaurs in the garden, let them hunt for fossils (chocolate coins), and decorate with jungle vines.

• Perfect for: Dino-obsessed ages 3–6

• Set-up tip: Dress your gazebo like a dig site with a sandpit outside and "archaeology tables" inside.

Pirate Party

Treasure hunts, walk the plank, and foam sword duels. Absolute carnage. They’ll love it.

• Perfect for: Ages 5–8, active groups

• Set-up tip: Use a chest of wrapped sweets as buried treasure under the gazebo and draw a big pirate map for guests to follow.

Teen Party Themes

Teen parties have levelled up. We’re talking TikTok trends, VIP setups, aesthetic lighting, and things that feel more like an event than a birthday. Whether it’s a small get-together or a full garden rave, one thing’s clear: teenagers don’t just want a party — they want a whole vibe.

That’s where a marquee or pop-up gazebo comes in. It gives them a space to style, stage, and shoot — and gives the grown-ups peace of mind knowing the chaos is (mostly) contained.

On-trend teen party ideas that work outdoors

Festival-Themed Garden Party

Glitter, henna, face paint, flower crowns, and good tunes. You can go all out with zones — food truck style buffet, chill tent, “live music” (aka someone’s speaker), and a firepit if it’s evening.

• Perfect for: Mixed ages, milestone birthdays, warm evenings

• Set-up tip: A 3x6m marquee becomes your main tent — add signage, festoon lighting, and low seating to create that Glasto-on-a-budget vibe.

Makeup & Self-Care Tent

More low-key but still very current. Think skincare stations, mirrors, face masks, and mani/pedi zones. Add magazines, soft seating, and calm tunes.

• Perfect for: Chill girls’ nights, birthdays, or exam season treats

• Set-up tip: Use a gazebo with open sides, cover tables with pastel cloths, and give each guest a spa-style headband.

Teen party planning tips

• Let them lead: You’re the backup dancer, not the headline act.

• Style matters: Even a basic setup feels elevated with decent lighting and coordinated colours.

• Think about what will get posted: That means ring lights, backdrops, neon signs, and snacks that look good on camera.

• Safety: If it’s going late, give guests somewhere to crash (or stagger collection times).

• Boundaries: Give them space, but let neighbours know it’s happening — and maybe drop off earplugs as a goodwill gesture.

  
  

BBQ & Summer Party Ideas

When the weather hits right and the grill’s on, it doesn’t take much to throw a great summer party. The key is making it look effortless — even if you’ve spent half the day chopping limes and stringing up fairy lights. Whether it’s a birthday, a casual get-together or the 7th “housewarming” of the year, summer garden parties are where memories get made.

A marquee or gazebo doesn’t just save you from the sun or the odd drizzle — it sets the scene, gives you structure, and keeps the party going when the temperature drops.

Summer party ideas worth stealing

The BBQ Social

Keep it simple: good food, plenty of drinks, music in the background. Lay out a few picnic blankets, bring out the deck chairs, and let it roll.

• Perfect for: Weekenders, bank holidays, low-effort good times

• Set-up tip: Use a gazebo to cover the grill or create a shaded seating space. Add battery lights for when it starts to get dusky.

  
  

Tropical Garden Party

Go bold: flamingos, pineapples, loud shirts, daft inflatable palm trees. It’s a warm-weather winner if you lean into the theme.

• Perfect for: Milestone birthdays, end-of-summer blowouts

• Set-up tip: Use printed sidewalls or bright bunting to dress your marquee. Serve tropical punch in coconuts (or plastic ones, we’re not monsters).

Planning tips for summer parties

• Always have shade: Even in the UK, sunburn sneaks up fast.

• Fridge space = limited. Invest in a cooler or use a paddling pool and ice for drinks.

• Offer non-alcoholic options — it’s a marathon, not a sprint.

• Make use of your BBQ Playlist — or build your own.

• Check out our full BBQ Checklist Guide for the full lowdown on hosting a proper one.

  
  

Adult Birthday Bash Ideas

There’s a point in life where birthdays stop being about jelly and start being about just one more glass and do you remember this song? Whether it’s a 30th, 40th, 50th or a well-earned 60th, adult birthdays in the garden let you go big without booking a venue — and with the right party shelter, you can build something unforgettable.

Adult party themes that work outdoors (and under canvas)

Classy & Low-Key

Not everyone wants a rave. Think small guestlist, string lights, charcuterie boards, and a curated playlist that leans into mellow gold.

• Perfect for: 30s and up, introverts with taste

• Set-up tip: A 3x4.5m marquee, dressed with voile and fairy lights, gives you the perfect semi-outdoor lounge feel.

Garden Pub Night

Build your own beer garden. Bench seating, quiz cards, pub snacks in bowls, and a mini-bar stocked with local ales and spirits.

• Perfect for: Sociable hosts, milestone birthdays, fans of pub quizzes

• Set-up tip: Turn the marquee into your pub snug — include signage, a dartboard if you’re brave, and even a “bar snacks” menu.

Throwback Party (Pick a Decade)

80s synths, 90s rave, Y2K sparkle, early 00s indie sleaze — choose your era and go all in. Dress code required. Embarrassing photos encouraged.

• Perfect for: 30–50-somethings who want nostalgia and chaos

• Set-up tip: Decorate your gazebo with themed memorabilia, and create a dance floor with coloured lights or glowsticks.

Murder Mystery Marquee

If you want something different, host a themed dinner party with characters, storylines, and dramatic accusations. Great for autumn or winter parties when you want to keep it cosy.

• Perfect for: Drama lovers, close-knit groups

• Set-up tip: A marquee with full sides creates that secretive, self-contained atmosphere. Use long tables and dim lighting for full theatre.

Adult party planning extras

• Set a time and an end time — and then ignore the end time

• Have options for people who don’t drink

• Set up an emergency “quiet zone” (often a gazebo corner with snacks and fewer people)

• Invest in heaters or fire pits for late-night warmth

• Prep a morning-after plan: coffee, leftover bacon, and a bucket for bottle caps

  
  

Wedding & Engagement Do’s

You don’t need a stately home or £20k to throw a memorable wedding or engagement party. With a bit of imagination, a garden you love (or can borrow), and a marquee that looks the part, you can create a celebration that’s personal, beautiful, and actually enjoyable — not just for the guests, but for the couple too.

Whether it’s a low-key engagement bash, a post-registry garden reception, or a full DIY wedding at home, your space becomes the story. And a well-dressed marquee is the difference between nice garden party and actual event.

Ideas for throwing romantic events at home

DIY Garden Wedding

Intimate, personal, and budget-friendly — a garden wedding lets you focus on what matters. Flowers from the local florist, speakers instead of a band, and food you actually like.

• Perfect for: Small weddings with big heart

• Set-up tip: Choose a premium marquee with linings, flooring and lighting. Add a separate drinks gazebo and a canopy over your ceremony space.

Engagement Garden Bash

This one’s all about the fizz and the photo ops. Keep it relaxed with nibbles and drinks, or go big with garden games and a playlist that covers your dating years.

• Perfect for: Newly engaged couples who want a fuss-free celebration

• Set-up tip: Use a 3x4.5m or 3x6m gazebo with light dressing — fairy lights, a “She said yes” sign, and maybe a Polaroid photo guestbook.

  
  

Evening Garden Reception

If you’ve tied the knot somewhere else, use your home or garden to carry on the celebration. The pressure’s off, the guest list is looser, and the drinks table is easier to reach.

• Perfect for: Post-wedding energy, mixed generations, great playlists

• Set-up tip: Use lighting to transition from day to night. A larger marquee lets you include tables, dance space, and maybe a projector for a photo slideshow.

Postponed-Now-Party

Plenty of couples have had to delay or scale back their big day. A marquee garden celebration lets you do it your way, without the formality or stress.

• Perfect for: “Finally married” couples or vow renewals

• Set-up tip: Keep it light-hearted. Lawn games, cocktails, and one good speech — yours.

Wedding & engagement party tips

• Have a backup for rain — guests will forgive drizzle, not soggy sandwiches

• Keep seating flexible — some people want to dance, others just want to talk

• Don’t try to DJ your own party unless you really want to

• If there are speeches, plan when they’ll happen — then everyone can relax

  
  

Fancy Dress & Themed Parties

If you’re throwing a party where people turn up dressed as 80s pop stars, astronauts, or the cast of Clueless, you need a space that says this is the party. A gazebo or marquee gives you the foundation to transform your back garden into anything from a disco den to a Wild West saloon.

Themed parties let guests step out of their day-to-day — which is half the reason they work so well. When it’s dark outside and you’re dancing in a toga next to your accountant mate dressed as a vampire, you’ve cracked it.

Theme ideas that actually get people excited

Decade Party

Choose your era — 60s flower power, 70s disco, 80s neon, 90s Britpop, or Y2K nostalgia. Bonus points if you theme the music and drinks to match.

• Perfect for: Milestone birthdays, hen/stag alternatives, just for fun

• Set-up tip: Use coloured lighting and themed props to match the era. A gazebo becomes your dancefloor or chill-out zone.

Movie or TV Theme Night

From Harry Potter to Stranger Things, Marvel to Moulin Rouge — if people love it, they’ll dress for it. Include a themed cocktail or food to match.

• Perfect for: Film buffs, group parties, dressing-up fanatics

• Set-up tip: Use sidewalls to create separate “scenes” or backdrops. Add a projector screen if you want to show clips or trailers.

Festival at Home

Turn your garden into a mini Glasto. Multiple zones, glitter bars, henna stations, music areas and food tents. Add a wristband for full effect.

• Perfect for: Teen and adult birthdays, post-wedding parties

• Set-up tip: One marquee = main tent. Add smaller gazebos as food/drink stalls or dressing areas. Think bunting, bold colours, and plenty of photo spots.

Planning tips for themed parties

• Choose a theme that gives people room to interpret — not everyone wants to dress as “a famous character from 1942”

• Provide a few accessories on arrival — hats, glasses, boas, badges

• Decorate in layers: lighting, fabric, props, and one standout feature

• Keep the tone light. The best themed parties don’t take themselves seriously
