Casinos have always gone hand in hand with fashion. While the classic image still leans toward tuxedos and evening gowns, the reality today feels far more varied.
In London especially, dress codes shift dramatically from venue to venue. You might walk into one casino wearing jeans and trainers without issue, yet find yourself turned away from another for not wearing a tie.
For that reason, understanding the differences matters.
Below, we break down five popular London casinos and exactly what to wear at each in 2026.
Hippodrome
To begin with, the Hippodrome sits firmly at the relaxed end of the spectrum. It offers one of the most accessible dress codes in London’s casino scene.
Rather than enforcing strict rules, the venue encourages guests to dress how they like, as long as they maintain an “acceptable standard”. In practice, this means jeans and trainers are perfectly fine.
As a result, you’re very unlikely to face any issues at the door based on your outfit.
What to wear:
- Dark jeans or chinos
- Fitted shirt or knitwear
- Clean trainers or smart shoes
Overall, aim for polished casual rather than overly relaxed.
Grosvenor Casino
Next, Grosvenor Casino introduces a slightly more structured approach with its smart-casual dress code. However, it still leans toward the relaxed side.
In simple terms, dress as you would for a night out at a good bar or restaurant.
That said, a few clear rules apply:
- Avoid scruffy or ripped jeans
- Skip manual workwear
- Limit sportswear unless tied to a live event
In fact, the overall vibe feels about as relaxed as casual as for Wimbledon and similar occasions.
Additionally, Grosvenor stands out for its regular poker nights, particularly Texas Hold’em, the most popular type of poker.
Interestingly, poker tables follow their own unwritten rules. Players often wear hoodies, caps, and even sunglasses. However, once you step away from the table, the wider smart-casual standard still applies.
The Palm Beach
Moving up in formality, The Palm Beach delivers a noticeably more refined experience. Located in the former Grand Art Deco ballroom of the Mayfair Hotel, the setting immediately raises expectations.
Although the dress code remains technically smart-casual, the standards feel higher.
- Men should wear collared shirts
- Smart jeans are acceptable
- However, trainers are not permitted
What to wear: A tailored shirt with a blazer and smart shoes works perfectly for men. Meanwhile, women can opt for a sleek dress or elevated separates.
Ultimately, this is where smart-casual begins to lean toward smart.
The Ritz Club
By contrast, The Ritz Club sits firmly in the world of formal luxury. Located beneath the iconic Ritz Hotel, the venue delivers a setting that feels straight out of a James Bond film.
Because of this, the dress code follows suit. Guests must wear smart formal attire that reflects the elegance of the surroundings.
- Men: suit jacket, collared shirt, formal shoes
- Women: cocktail dresses or evening wear
Importantly, jeans, trainers and sportswear are not allowed under any circumstances.
In short, this is a place where dressing up isn’t optional, it’s expected.
Les Ambassadeurs
Finally, Les Ambassadeurs represents the pinnacle of London’s casino scene. Known worldwide for its exclusivity, it regularly attracts celebrities, high-net-worth individuals and royalty.
Unsurprisingly, the dress code matches the setting.
As outlined in this dress code guide, expectations remain firmly formal:
- Men: suit and tie required
- Women: dresses or evening gowns
Here, casual dressing simply doesn’t work. Instead, think classic, elegant, and polished from head to toe.
Final Thoughts
Ultimately, London’s casino scene reflects the city itself, diverse, dynamic, and style-conscious.
While some venues embrace relaxed dress codes, others maintain strict standards rooted in tradition. Therefore, choosing the right outfit can shape your entire experience.
When in doubt, lean slightly more formal. Not only will you feel more confident, but you’ll also avoid any awkward moments at the door.
After all, in a city where style speaks volumes, dressing well ensures you stand out for the right reasons.
