Dark Jeans and a Blue Oxford Shirt
Dark jeans and a blue oxford shirt is the safest casual dinner outfit there is. Dark denim looks dressier than light or ripped jeans, and a crisp oxford adds a collar without feeling stiff.
The Emily Post Institute describes casual dress for men as “khakis or good jeans (clean, no holes)” with loafers, sneakers or sandals. Dark, clean jeans and a collared shirt sit right in that zone, with room to dress up or down.
Restaurants use dress codes loosely, so it helps to know roughly what each level means. Here’s how they compare.
| Dress Code | Pants | Top | Shoes |
|---|---|---|---|
| Casual | Clean jeans or khakis | Tee, polo or casual shirt | Clean sneakers, loafers, sandals |
| Smart or dressy casual | Dark jeans, chinos, trousers | Oxford, knit polo, sweater | Loafers, suede shoes, clean leather sneakers |
| Business casual | Chinos or trousers | Button-down shirt, optional blazer | Loafers or leather shoes with socks |
| Smart dinner | Tailored trousers | Shirt with blazer or sport coat | Leather loafers or dress shoes |
If you’re unsure, dress one step up from what you’d wear at home. It’s easier to roll up sleeves or take off a blazer than to dress up an outfit on the spot.

Black Jeans and a Black Shirt
Black jeans and a black shirt is a sleek, modern dinner outfit. The all-black look reads polished at night and works for cocktail bars, city restaurants and late dinners.
Make sure the blacks match in depth. Faded black jeans with a deep black shirt can look tired.
✅ Do This
Pick a shirt with a little texture or sheen, so the outfit has depth instead of looking flat.
🚫 Skip This
Don’t wear scuffed or faded black shoes, because worn leather stands out against crisp black clothes.
A silver watch or simple ring is enough jewellery here. One metal accent looks better than several.

Navy Blazer With Grey Trousers and an Open-Collar Shirt
A navy blazer with grey trousers and an open-collar shirt is the smartest casual dinner outfit. It looks put-together without a tie, so it fits nicer restaurants that aren’t truly formal.
On the AskAndy About Clothes forum, a member giving advice on casual dinner dress recommended a navy blazer because it goes “with anything that is not navy.” Grey trousers are the classic partner.

An unstructured blazer feels softer and more relaxed than a stiff suit jacket. It’s the better pick when the dress code says “casual.”

Knit Polo With Tailored Trousers
A knit polo with tailored trousers looks refined but relaxed. The fine knit feels dressier than a cotton piqué polo, and tailored trousers lift it above weekend wear.
Where the Polo Shirt Came From
According to Wikipedia’s entry on the polo shirt, the tennis player René Lacoste designed a short-sleeved piqué cotton shirt to replace stiff tennis clothes, and first wore it at the 1926 U.S. championship. The button-down collar seen on many casual shirts came earlier, invented by polo players in the late 19th century to stop their collars flapping in the wind.
Tuck the polo in or leave it out depending on its length. A knit polo that ends at the belt can go untucked, but a longer one looks neater tucked.
05
OF 23
Linen Shirt With Chinos
A linen shirt with chinos is a cool, breezy summer dinner outfit. Linen breathes in the heat, and chinos look smarter than shorts without feeling heavy.
Roll the sleeves to the forearm for a relaxed feel. Leave one or two top buttons open, but not more.
💬 Linen Wrinkles Are Part of the Look
Linen creases within minutes of wearing it, and that’s expected. A light crumple looks relaxed, but iron or steam it before you leave so it starts fresh.
06
OF 23
Tailored Shorts With a Camp-Collar Shirt
Tailored shorts with a camp-collar shirt can work for a casual summer dinner. Neat chino shorts and a proper collared shirt look intentional, not lazy.
The shorts should be tailored and end a few inches above the knee. Loafers or leather sandals dress them up more than sneakers.
Skip It If the Restaurant Has Any Dress Code
Shorts are fine at a beach shack or a casual terrace, but many sit-down restaurants expect long trousers in the evening. If you’re not sure, choose linen trousers instead.

Merino Crewneck Over a Collared Shirt
A merino crewneck over a collared shirt is a smart, cosy fall dinner outfit. The collar peeking out adds polish, and fine merino feels soft and warm without bulk.
Fine merino layers cleanly over a shirt. Chunky knits bunch up and make the collar look messy.
08
OF 23
Brown Quarter-Zip With Chinos
A brown quarter-zip with chinos is an easy, relaxed outfit for casual dinners. The zip collar looks a little smarter than a crewneck, especially with a shirt collar underneath.
Brown and cream feel warm and autumnal. Suede chukka boots match the relaxed vibe.
📌 Knit Quarter-Zips Look Smarter Than Fleece Ones
A fine-knit wool or cotton quarter-zip looks right at dinner, while a fleece or athletic quarter-zip looks like gym wear. Choose a knit with a clean, flat collar.

Cream Cable Knit With Brown Trousers
A cream cable knit with brown trousers is a classic old money-inspired dinner outfit. The soft cream and rich brown look understated, polished and warm.
Quality fabrics matter more than logos here. Wool trousers and a good knit do the talking.
✅ Copy This Old Money Dinner Outfit
- A cream or ivory cable-knit crewneck
- Tailored brown wool trousers
- A brown leather belt
- Brown suede penny loafers
- A simple watch with a leather strap

Turtleneck With a Blazer
A turtleneck with a blazer is a sleek winter dinner outfit. The fine-knit turtleneck replaces a shirt and tie, so it looks dressed up but relaxed.
Black or charcoal turtlenecks look the most modern. Cream or camel feel softer and warmer.
💡 The “Turtlenecks Look Too Casual for Dinner” Myth
Myth: A turtleneck isn’t smart enough for a nice dinner.
Reality: A fine-knit turtleneck under a tailored blazer looks as polished as a shirt and tie in many restaurants, especially in winter.

Wool Overcoat With a Sweater and Dark Jeans
A wool overcoat with a sweater and dark jeans is a polished outfit for cold dinners. The overcoat makes even simple jeans look smart when you walk in.

Once you take off the coat, the sweater and jeans should still look good on their own. Choose a knit that fits well rather than a baggy one.

Suede Blouson Jacket With Trousers
A suede blouson jacket with trousers is a smooth, relaxed dinner outfit. The soft suede jacket looks rich and textured, and it’s more interesting than a plain cotton jacket.
A white tee keeps it relaxed, while a knit polo makes it a little smarter. Clean white leather sneakers keep the casual feel.
Suede doesn’t like rain. Keep this jacket for dry evenings, or treat it with a suede protector spray.

Quilted Gilet Over an Oxford Shirt
A quilted gilet over an oxford shirt is a relaxed outfit for country pubs and casual dinners. The gilet adds warmth to your core and looks a little sharper than a hoodie or sweater.
Navy, olive and brown are the classic gilet colours. Pair them with chinos and leather boots.
It can feel warm indoors, so take the gilet off once you sit down. The oxford shirt should look good on its own.

Business Casual Dinner Outfit Straight From Work
A business casual dinner outfit straight from work can be adjusted in a few minutes. A few small changes make a work outfit feel more relaxed for dinner.
Turning a Work Outfit Into a Dinner Outfit
Most office outfits only need small tweaks to feel right at dinner. These changes take less than five minutes.
Take off the tie and open the top button of your shirt.
Roll your sleeves neatly to the forearm.
Swap a stiff work blazer for a softer jacket, or carry it.
Change formal shoes for loafers if you keep a pair at work.
Add a watch or simple accessory that feels more personal.

Pastel Green Shirt With White Trousers
A pastel green shirt with white trousers is a fresh, cheerful spring dinner outfit. Soft green looks lighter and more interesting than a white shirt.
Tan suede loafers or brown shoes add warmth to the light colours. Black shoes look too heavy with white trousers.
⚠️ White Trousers Show Every Spill
Red wine, sauces and coffee stand out instantly on white. Keep a stain pen handy, and order carefully.
16
OF 23
Denim Shirt With Grey Trousers
A denim shirt with grey trousers mixes rugged and smart. The casual denim shirt looks more grown-up with tailored grey trousers than with jeans.
Avoid denim on denim unless the shades are very different. A denim shirt with trousers is easier to get right.
Dark brown chukka boots bridge the rugged and smart sides of the outfit. Suede or leather both work.
17
OF 23
Henley With a Leather Jacket
A henley with a leather jacket is a confident outfit for casual nights out. The henley feels softer than a tee, and the leather jacket adds edge.
Dark jeans and leather boots finish the look. Keep the henley’s buttons partly open.
BEFORE:
A faded graphic tee, light ripped jeans and old running shoes under a leather jacket.
AFTER:
A charcoal henley, dark grey jeans and black leather boots under the same leather jacket.

First Date Dinner Outfit
A first date dinner outfit should look like you made an effort without trying too hard. A navy knit polo, dark jeans and clean white leather sneakers hit that balance.
Fit matters most. Clothes that fit well look better than expensive clothes that don’t.
Wear something you’re comfortable in and have worn before. A brand-new outfit can feel stiff on a night when you want to relax.

Casual Dinner With Friends Outfit
A casual dinner with friends outfit can be simple and comfortable. A soft sweater with jeans and clean sneakers looks relaxed but still put-together.
AskAndy forum members point out that jeans with a sweater or casual shirt suit casual places, especially after a casual day. That’s exactly the setting for most dinners with friends.
Treating “Casual” as Gym Clothes:
Even a relaxed dinner deserves a step up from sweatpants and a hoodie. Swap athletic wear for jeans, a knit and clean shoes, and you’ll feel more comfortable in any restaurant.
20
OF 23
Rehearsal Dinner Outfit
A rehearsal dinner outfit sits between casual and wedding-formal. A light blazer, an open-collar shirt and chinos look smart for photos without competing with the wedding day.
Light grey, tan or navy blazers suit spring and summer rehearsal dinners. Darker blazers work better in fall and winter.
💡 Check the Invitation for a Dress Code
Rehearsal dinners vary a lot, from backyard barbecues to formal restaurant dinners. If the invitation doesn’t say, ask the couple or a family member.

Monochrome Casual Dinner Outfit for Shorter Men
A monochrome casual dinner outfit for shorter men uses one colour from top to bottom. A navy top and navy trousers create one long line, which makes you look taller.
Slim, well-hemmed trousers with no extra fabric at the ankle help too. Big breaks or stacking cut the leg short.
📌 One Colour Top to Bottom Adds Height
Contrast at the waist splits your body in two, which can make you look shorter. Matching colours, or a darker top and trousers in the same family, keeps the line long.
22

Teen Casual Dinner Outfit
A teen casual dinner outfit should look neat but comfortable. A crewneck sweater over a tee, dark jeans and clean sneakers work for family dinners and birthdays.
Clean, fitted clothes matter more than labels for teens. Make sure the sneakers are clean and the jeans aren’t ripped.
💬 A Collar Instantly Smartens a Teen Outfit
For a slightly dressier dinner, swap the tee for a collared shirt under the sweater. It’s an easy way to look more grown-up.

Boys’ Casual Dinner Outfit for Family Restaurants
A boys’ casual dinner outfit for family restaurants should be neat and comfortable. A short-sleeve button-up shirt with chinos and canvas sneakers looks smart without being stiff.
Choose soft, easy-care fabrics, since kids fidget and spill. Chinos with an elastic back waist are comfortable for sitting through a meal.
💡 Pack a Spare Shirt for Little Kids
Spills happen at kids’ dinners. A spare shirt in the car or bag saves the evening if something lands on the first one.
