TL;DR: Smart casual is the usual supper club dress code, and the easiest way to calibrate is the "friend's home" test: dress like you're heading to a nice dinner at a friend's place. There's no single right answer, and what feels right shifts with the venue, the city, and the season. If you book through Timeleft, the app reveals your venue name and address the day before, so you can see the room before you pick an outfit.
The most common first-timer dress code story goes roughly like this. Someone shows up to a relaxed underground dinner in a blazer, host in a hoodie, spends the first hour feeling overdressed, and by the second hour has stopped thinking about it entirely. Nobody mentioned the blazer. That pattern tells you more about supper club attire than most dress code guides do. Every person in that room made the same guess about the venue, with the same incomplete information, and it mostly worked out.
Supper clubs run the range from secret dinners in someone's apartment to polished private clubs with stated dress codes, so the question "what should I wear to a supper club" doesn't have one answer. It has a framework, and once you have it, the whole decision takes about a minute.

Why the outfit matters less than you think
Here's the psychology nobody mentions in dress code guides. At a supper club, the outfit signals intent. Most venues and fellow diners tend to read effort and presence over perfection. A table of strangers typically values genuine participation over strict adherence to an unstated code.
The asymmetry is gentler than most first-timers fear. One restaurant industry guide notes that being a little overdressed "costs you almost nothing," since it reads as respect for the occasion and for the host. The same guide calls smart casual "the most common modern restaurant code and the most misread," because it means elevated clothing rather than literally casual. Getting the formality slightly wrong barely registers. The only real mistake is spending so long on the decision that it outlasts the dinner itself.
What smart casual actually means
Smart casual is the code most venues default to, and it's broader than it sounds. MasterClass's dress code guide describes it as well-fitting, put-together clothing like button-downs, blouses, chinos, and dark-wash jeans, sitting between dressy casual and business casual. In practice, that covers most of what people already wear to a nice dinner.
The friend's home test
A practical starting point is the friend's home calibration. Dress the way you would for a nice dinner at a friend's place, the kind of dinner party where you'd reach for something considered but not formal, not a full suit or formal gown. That image is a useful anchor when the venue type is unknown.
The supper club dress code, decoded
Not all supper clubs are the same room. A secret dinner in a private apartment, a pop-up in a gallery, and a members' club with a posted dress code are three different problems, and each one calibrates differently.
Secret and underground dinners lean relaxed by design. The venue is often someone's home or a temporary space, and the format rewards ease over ceremony. One long-running secret supper club tells guests simply to wear whatever you're comfortable in, adding that some guests even make their private dinners a black tie event by choice. The point is that the host sets no bar. A supper club outfit for a secret dinner works best when it feels like your best version of a normal evening, with one considered detail rather than a head-to-toe statement.
Pop-ups and temporary kitchens
Pop-ups and temporary kitchens add practical considerations on top of the social ones. You might be standing for part of the evening, and seating is often communal benches rather than individual chairs. Smart casual works for most city pop-ups, and gallery or loft events lean even more laid-back, per Devour Destinations' pop-up guide. Prioritize footwear you can stand in, because nothing deflates a good evening like counting down the minutes until you can take your shoes off.
Private clubs and members' venues are the one category where a stated dress code is real and enforced. Older private clubs tend to require suits and ties for men, and Lisa Grotts' private club guide notes that guests who fall short of the dress code may be able to borrow a jacket and tie from the club's stock, but no club carries trousers to substitute for jeans. If the venue publishes a code, follow it literally and check with your host before arriving if you're unsure.
Timeleft dinners
Timeleft is built to remove the guessing problem entirely. The day before your dinner, the app reveals your venue, so you know whether you're walking into a neighborhood bistro or somewhere with white tablecloths before you've opened your closet. Timeleft's venue network spans 20,000+ hand-selected restaurants across 52 countries and 200+ cities, and the practical range runs from relaxed neighborhood bistro to polished city restaurant. Smart casual is the standard code across the bistro and city restaurant range that Timeleft's venue network covers.
Supper club attire by venue type
When a supper club does publish a code, the vocabulary is simpler than it looks, and real venue policies show how concrete it gets:
- Smart casual: Elevated separates, dark jeans allowed, no beachwear or gym wear. This is the default at most modern venues.
- Cocktail attire: A suit or a dressy dress. Rarer, and usually attached to hotel or fine-dining settings, where Hotel Seymour's supper club guide notes a luxury venue may call for tailored suits or evening gowns.
- Come as you are: Everyday clothes, but not literally anything. As Brogle's dress code explainer notes, the same items that feel out of place in a London dining room can read as perfectly normal in Lisbon or Barcelona in July. Climate and city culture shift the floor.
Actual posted policies are even more reassuring. For men, Supperclub BTR bans sandals, hats, shorts, and athletic wear while explicitly allowing dressy sneakers. The Twelve Thirty Club permits well-kept jeans and only asks guests to limit beach attire and sportswear. Untitled Supper Club in Chicago reportedly draws the line at t-shirts, shorts, sandals, and gym shoes. Notice what none of them ban. Normal, clean, comfortable clothes.
The one-outfit strategy for secret venues
When you don't know the address until the day before, pack one versatile outfit and commit to it:
- Bottom: Dark jeans or tailored trousers
- Top: A good shirt, blouse, or quality knit
- Layer: Something you can remove (blazer, cardigan, or jacket)
- Shoes: Comfortable for standing and sitting (loafers, ankle boots, or clean leather sneakers)
Themed immersive dinners are the exception, since some encourage full character dress, per Devour Destinations' etiquette guide, but those announce themselves well in advance.
The dressy sneaker exception
The one genuine gray area is footwear. Clean, minimalist leather or suede sneakers pass at most modern venues, with the practical test being whether they look new or look like you've run a 5K in them, per this NYC dress code guide. One clubwear guide draws the casual floor at clean, dark-colored sneakers, and running shoes and gym trainers sit in a different category entirely, which MasterClass's smart casual guide describes as too casual for the attire.
Signs you have overthought the dress code
There's a specific kind of overthinking that supper clubs trigger, because the venue is unannounced, the other guests are unknown, and the outfit becomes the one variable that feels controllable. The tell is when your outfit planning starts taking longer than the dinner itself.
The wedding test
If your outfit would be appropriate at a formal wedding, save it for one. Unless the venue publishes a cocktail or black-tie code, full formality is more than most rooms need. That said, nobody minds if you enjoy dressing up, so the question is always the room, not a universal rule.
The comfort check
If you catch yourself planning around how the outfit will be perceived rather than whether you'll be comfortable for three hours, pull it back one notch. The goal at a table of people you've never met is to blend in enough that the conversation becomes the interesting thing about you. An outfit that keeps announcing itself competes with that.
Outfit ideas that work across venues
Everything above compresses into a handful of formulas. These work across secret dinners, pop-ups, private clubs, and Timeleft tables, and each one survives a venue reveal that turns out fancier or more casual than expected. The table below offers two approaches per venue type: one leaning more structured, one more relaxed. Both travel across venue types.
| Venue type | More structured | More relaxed |
|---|---|---|
| Secret or underground dinner | Dark jeans, oxford or button-down, suede boots or clean leather sneakers | Dark jeans, quality knit or henley, ankle boots, light jacket |
| Casual pop-up | Tailored trousers, pressed shirt or blouse, clean minimalist sneakers | Chinos or relaxed trousers, soft top, comfortable flats or low boots |
| Private club | Blazer, pressed shirt or blouse, smart trousers, leather shoes | Quality knit or silk top, wide-leg or tailored trousers, loafers. A jumpsuit or dress works too |
Balance is the formula behind every formula
Pair one dressier piece with one relaxed piece and you land in the right zone almost automatically. A blazer over a plain tee, heels with jeans, a silk top with everyday trousers. MasterClass recommends exactly this technique for heels, and the same logic works for footwear swaps, dressing down a polished look with clean sneakers when the venue runs casual.
Build any of these outfits in three steps:
Start with the bottom: Dark jeans or tailored trousers anchor every formula and travel across venue types.
Add a polished top: A collared shirt, blouse, or quality knit signals effort without formality.
Layer for flexibility: A blazer, jacket, or cardigan lets you adjust on arrival once you read the room.
One outfit that covers most dinners
If you want one answer to keep, it's dark-wash jeans or tailored trousers, a collared shirt or good blouse, a removable layer, and clean leather shoes or minimalist sneakers. That combination rarely goes wrong across any supper club type, and it converts between venue types by adding or removing the layer. Coming straight from the office? Swap the dress shoes for clean sneakers or loosen the collar, and you're calibrated.
How much dress codes vary
Only a minority of venues publish restrictions, and they tend to be upscale spots like Supperclub BTR and Untitled Supper Club in Chicago, which call out items such as athletic sneakers, shorts, and sandals. Those are the rules of those particular rooms, not a standard for every supper club or for Timeleft's venue network. City variation is real but smaller than people fear. Parisian restaurants are largely casual by local standards, with a jacket and tie rarely required, per Le Petit Paris, and travelers on Rick Steves' forum note that anything beyond beachwear passes in most of Europe. Timeleft runs dinners in Paris, Berlin, Leeds, Toulouse, Nantes, and Montpellier, and the universal outfit travels to all of them.
How Timeleft handles the whole question
The day-before reveal is designed to kill the two worst parts of the supper club outfit problem at once. You can't overthink a decision you only have a day to make, and you can't get the venue wrong when Timeleft tells you where you're going. You can book an event in a few minutes, up to 13 hours before it starts, which means a Tuesday decision can become a Wednesday dinner. The subscription is $19.99/month in the US, you pay for food and drinks separately at the venue, and once you subscribe you can attend as many events as you like that month. You can also set dietary preferences in the app before you book.
The part that makes the evening work has nothing to do with fabric. It's showing up relaxed enough to talk to strangers, which is the thing diners mention again and again.

Here's what matters. Nobody at your table will remember your outfit. They'll remember whether the conversation went somewhere none of you saw coming. Take the personality quiz and subscribe, and let the day-before reveal handle the outfit question for you.
FAQs
What should I wear to a supper club if there's no dress code listed?
Default to smart casual, dark jeans or tailored trousers, a collared shirt or blouse, and clean shoes. If the venue is secret or underground, lean toward the relaxed end of that range.
Can I wear jeans to a supper club?
Yes, at most supper clubs. A handful of the more upscale venues listed earlier do call out distressed denim specifically, but for the majority of secret dinners, pop-ups, and Timeleft tables, jeans are a completely normal choice. You'll see them at Timeleft dinners constantly.
What if I'm coming straight from work?
Work attire mostly converts with one swap, trade dress shoes for clean minimalist sneakers, or lose the tie and add a relaxed layer. Pairing one dressy piece with one casual piece keeps you in the smart casual zone.
Is supper club attire different by city?
Slightly. Paris and most of Europe run more casual than American diners expect, while US venue policies tend to spell out bans (shorts, sandals, gym shoes) more explicitly. The universal outfit formula works in every city Timeleft operates in.
What do people wear to Timeleft dinners?
Smart casual, calibrated to the venue the app reveals the day before. The universal outfit formula earlier in this guide applies, and if anything about the evening surprises you, Timeleft's help center covers what to do and how to find your table before your first dinner.
