DateableWhat smart casual means, and why jeans do not count
Smart casual is a jacket with chinos or tailored trousers, or a dress, skirt or smart trousers. The jacket does most of the work.
Smart casual is by far the most common dress code: a jacket with chinos or tailored trousers for you, or a dress, skirt or smart trousers if you are dressing as a woman. The jacket does most of the work, shoes decide whether the outfit reads smart, and if you are unsure, a quick call to the venue settles it. 1 Our guide to dress codes covers the full range from white tie to casual, so you can see where smart casual sits.
What smart casual is not
Smart casual does not mean jeans and a nice top. Even designer denim reads as too informal for most venues that use this dress code, so leave denim in the wardrobe for other nights. If the invitation says smart casual and you arrive in jeans, the venue staff will see you as underdressed. Denim is for casual dates: coffee shops, parks, walks, or somewhere where nobody expects formality.
It is also not business wear. A business suit or a full lounge suit is more formal than smart casual. If the dress code says smart casual and you show up in a three-piece suit or a jacket with a tie, you are overdressed. Smart casual sits between casual and formal. The point of smart casual is to look polished without looking like you are heading into the office.
And it is not cocktail attire. A cocktail dress, which is usually knee-length or shorter and more decorated than everyday clothes, is more formal than smart casual. So is an evening gown. Smart casual is simpler and plainer.
The jacket does most of the work
Put a structured blazer over a plain shirt or jumper and chinos, and you read as smart casual. The jacket transforms what would otherwise be weekend clothes into an outfit for somewhere nicer. The fit matters more than the price: a well-fitted blazer in a neutral colour (black, navy, grey, camel) works with almost anything underneath.
If you are dressing as a woman, a blazer over a dress does the same work. A simple shift dress or a shirt dress becomes smart casual when you add a structured jacket. Without the jacket, it reads casual instead.
Shoes decide whether you look smart
Your shoes are what makes or breaks the outfit. Trainers, canvas shoes or scuffed flats read as casual. If you are going somewhere that has called for smart casual, wear leather shoes: oxfords, brogues, loafers, or court shoes if you are dressing as a woman. They do not have to be expensive, but they should be clean and well-maintained. A £40 pair of leather shoes that are polished reads smarter than a £200 pair of trainers.
If you wear the right shoes, the rest of the outfit lifts. If you wear casual shoes, the rest of the outfit reads casual no matter how smart the rest of you looks. Shoe colour should match or complement the rest of your outfit: black shoes with black trousers, brown with camel, navy with cream. Anything too bright or patterned reads playful rather than smart.
Polish your shoes before you go out. Scuffed leather, dirt in the crevices or a worn heel show that you did not make an effort. It takes five minutes and changes how polished you look overall.
What you wear underneath the jacket
- A plain shirt in white, light blue, cream or a soft neutral
- A fine-knit jumper or sweater in black, navy, grey or burgundy
- A simple blouse without busy patterns
- Tailored trousers in black, navy, grey, camel or cream
- Chinos (the more structured, the better)
- A skirt that falls below the knee, in a neutral or dark colour
- A dress in a solid colour, not too short
Avoid loud patterns, visible logos, sheer fabric without a slip, short hemlines and anything that reads beachy or sporty. You are aiming for understated and put-together, not playful or casual. The idea is to look like you have made an effort without looking like you have tried too hard.
Fabric matters too. Cotton, linen, wool and silk all read smart. Cheap synthetics, see-through materials, and anything pilled or bobbled look like you picked it off the floor. If you are washing and wearing the same top every time you go out somewhere nice, it will start to look shabby. Invest in two or three good pieces and rotate them.
When to call and ask
Your date suggested dinner at a restaurant you have never been to, or a venue you are not sure about. Text them before the day and ask. Most people appreciate it. If you are planning a first date, asking about the dress code is one of the sensible questions to ask early.
I'm not sure what the dress code is like where we are meeting. Is it smart casual, or somewhere more relaxed?
If they say smart casual and you still feel uncertain, call the venue itself. Staff answer hundreds of questions about dress code every week and will not judge you for asking.
If you are meeting somewhere upmarket
A fine-dining restaurant, a private club or a luxury hotel are places where smart casual is the minimum. They may expect something closer to lounge suit (business attire) than casual. If you are meeting your date somewhere like that for the first time, lean towards the more formal end of smart casual. A jacket is essential, and shoes must be leather and polished. Read our guide to first dates for more about choosing and preparing for a venue.
If it turns out to be a casual rooftop bar instead, you will be more dressed than everyone else, but you will read well. It is better to overdress slightly than underdress when the venue is upmarket.
Accessories help you look finished
A neat handbag or a structured messenger bag, a leather belt, a simple necklace or watch, and minimal jewellery finish the outfit. Accessories do not have to be expensive to work: leather and structured shapes read smarter than soft bags, loose scarves or costume jewellery.
Avoid bright colours, large logos and anything too trendy. You are going for timeless and refined, not fashionable.
