London hen nights aren’t just about dancing until dawn-they’re about showing up in a way that turns heads, sparks laughs, and makes the night unforgettable. The right themed dress code doesn’t just set the tone; it turns a group of friends into a walking party. Whether you’re going for glam, retro, or downright silly, the key is balance: fun without looking like you raided a costume shop, classy without being boring.
Why Dress Codes Matter on a London Hen Night
London’s nightlife scene is huge. You’re not just walking into one bar-you’re hitting five, maybe six, in one night. Each venue has its own vibe: a speakeasy in Shoreditch, a rooftop lounge in Canary Wharf, a live music pub in Camden. If everyone shows up in jeans and a t-shirt, you blend in. But if you show up in a coordinated theme? You own the room.
Themed dress codes also solve a real problem: decision fatigue. When you’re planning a hen night with 10+ people, nobody wants to argue over what to wear. A clear theme takes the guesswork out. It’s also a killer photo opportunity. Instagram feeds love a well-executed theme. And let’s be honest-when the bride walks in wearing a 1920s flapper dress and the whole squad’s in sequins, you’re not just dressed up-you’re part of the spectacle.
Top 5 Themed Dress Codes That Work in London
Not all themes translate well to the city’s streets and venues. Some are too loud, too expensive, or too hard to move in. These five have been tested across dozens of London hen nights and consistently deliver.
- 1920s Gatsby Glam-Think feather headbands, drop-waist dresses, long gloves, and bowler hats for guys. It’s classy, timeless, and perfect for cocktail bars like The Alchemist or The Wolseley. Bonus: it’s easy to find vintage-inspired pieces in London’s thrift stores.
- Neon Night-Blacklight-friendly outfits, glow sticks, neon leggings, and fluorescent crop tops. Great for clubs like Ministry of Sound or Electric Brixton. Make sure everyone wears white or light colors so the UV lights really pop. Avoid cheap plastic accessories-they break too fast.
- Movie Star Red Carpet-Even if no one’s a Hollywood star, everyone can channel one. Think black tie, sequins, faux fur stoles, and statement heels. Bring a mini champagne bottle to pose with like a paparazzi shot. This theme works in upscale venues like The Savoy or The Ivy. It’s elegant but still playful.
- 80s Power Dressing-Shoulder pads, leg warmers, bold prints, and big hair. Think Madonna meets Dynasty. It’s fun, nostalgic, and surprisingly easy to pull off with things you already own. Perfect for retro bars like The Lock Tavern or The Eagle. Pro tip: pair a blazer with a crop top for that authentic 80s contrast.
- Under the Sea-Mermaid tails (with detachable bottoms for dancing), fishnet tights, seashell accessories, and blue or silver makeup. Works surprisingly well in venues with dim lighting and water features, like The Canary or The Bluebird. Avoid full-body tails-they’re a nightmare on the dance floor.
What to Avoid
Some themes look great on Pinterest and terrible in real life. Here’s what to skip:
- Too revealing-London venues have dress codes. A thong over fishnets might get you turned away at the door. Keep it sexy, not scandalous.
- Overly complicated costumes-If it takes 20 minutes to put on, it’s not worth it. You’ll be late, frustrated, and stuck in a queue outside a club.
- Themes that require props-Unless you’re renting a van, don’t bring giant inflatable dolphins or foam swords. They get confiscated, broken, or lost.
- Matching outfits that don’t fit-No one wants to be the only person in the group who looks like they’re wearing a child’s costume. Stick to one color palette or style, not identical outfits.
How to Plan the Theme Without Stress
Start with the bride’s vibe. Is she a classic romantic? A party animal? A vintage lover? That’s your anchor. Then pick a theme that matches her personality-not what the group thinks is funny.
Use a group chat to vote on 2-3 options. Don’t let one person dominate. Give people a week to find or rent outfits. Include a budget range: £20-£50 is realistic for most themes. Suggest places like Rent the Runway, Vinted, or local costume shops in Camden or Soho.
Assign a theme captain-someone who’ll send out outfit examples, check-in reminders, and a final dress code checklist a day before. Include a note: “No flip-flops. No sports jerseys. No socks with sandals.” Simple rules prevent chaos.
Where to Shop for Hen Night Outfits in London
You don’t need to order online. London has great local options:
- Camden Market-Best for neon, punk, and 80s gear. Quick, cheap, and full of character.
- Topshop (Oxford Street)-Great for sequins, bodycon dresses, and statement accessories.
- Vintage & Co. (Soho)-Real 70s-90s pieces, not cheap copies. Perfect for Gatsby or Power Dressing themes.
- Amazon Prime-Surprisingly good for last-minute items like glitter tights, feather boas, or faux fur wraps.
- Thrift stores like Oxfam or The Salvation Army-Hidden gems for unique pieces. Spend an afternoon hunting.
Pro Tips for Pulling It Off
- Wear nude or black underwear-No one wants to see panty lines under a sheer dress.
- Bring a small bag-Keep essentials: lip gloss, tissues, a spare pair of shoes, and a mini spray bottle of perfume.
- Comfort matters-You’ll be walking miles. Wear heels you can dance in, or bring flats to swap into after the first venue.
- Group photo at the start-Take one before the night begins. You’ll all want it later.
- Respect the venue-Some places charge extra for glitter or confetti. Ask first.
What Happens When Things Go Wrong
Someone forgets their outfit? No problem. Borrow a scarf, tie a glitter belt around jeans, or buy a £5 feather boa from a street vendor. Someone’s too shy? Let them wear a themed accessory instead-like a tiara or a neon headband. The goal isn’t perfection. It’s connection.
Hen nights are about celebrating someone you love. The outfit is just the icing. The real magic happens when the whole group laughs, dances, and remembers this night for years.
What’s the most popular hen night theme in London right now?
Right now, 1920s Gatsby Glam and Neon Night are the top two. Gatsby works for upscale venues and photo ops, while Neon Night dominates club-heavy itineraries. Both are easy to pull off without breaking the bank.
Can we mix two themes together?
Yes, but only if they’re compatible. For example, 80s Power Dressing + Neon can work-think shoulder pads in fluorescent pink. But avoid mixing Gatsby with Under the Sea. It confuses the vibe and looks messy in photos.
Do we need to buy new clothes for the theme?
Not at all. Most themes can be done with what you already own. A black dress + glitter = Red Carpet. Jeans + a sequin top = Neon Night. Thrift stores and rental services are your friends if you need something specific.
What if the bride doesn’t want to dress up?
That’s fine. Let her be the ‘elegant outlier’-she can wear a simple black dress or tailored jumpsuit while everyone else is themed. She’ll still stand out, but in a calm, confident way. Don’t pressure her.
Are themed hen nights still trendy in 2025?
Yes, and they’re evolving. Couples now mix themes with personal touches-like a ‘Harry Potter’ theme for a book-loving bride, or ‘London Underground’ with tube map prints. It’s less about copying trends and more about reflecting the bride’s personality.
When planning a hen night in London, the best themes don’t just look good-they feel right. They turn a night out into a shared story. Pick one that matches the bride’s spirit, keep it practical, and let the fun happen naturally. The outfit? It’s just the beginning.
